This is extremely dumb to most of you

[Revo Rancher]

Geeez, I go away to do some work and take a 10 minute nap and spitfir is running in the A-mains! Great! You are going to shock your dad because the last time he saw the rig he got blisters from trying to help you start it.

When you get time to try the next step, do the same thing, 3 second throttle runs, then brake, but this time vary it from 1/3-1/2 throttle. Do this one tank. Right now you are thinking, "Why can't I lean it?". Believe it or not, everytime the tank gets low on fuel the fuel mixture gets leaner in the carb (long explanation, don't ask why). So, if the car makes it through one more tank of 1/3-1/2 throttle blips without engine trouble, then we will lean it some more since it just ran lean at the end of that last tank and ran fine.

Add another tank of fuel, turn the top end needle, usually the one highest and easiest to see, 1/8th of a turn to the right or clockwise. Go through that tank with 1/2 throttle, 3 second bursts. If all is well, and you still have blue smoke coming out the pipe, lean it another 1/8th and do 5 second half throttle blips. If all is well, try another tank and see if you can get as much throttle as you can handle up to 3/4.

If you can't, we'll take you to the next step. If you can, then we'll try to performance tune it and then you will be on your way.

In the future, once it is broken in, it should start within 2-3 pulls, idle nice, and only need one needle adjustment, barely, one way or the other. You are lucky, you are in Florida where the weather is much more consistent. (Like us in So Cal)

BTW, somewhere along here it is entirely possibly you're break-in glow plug may foul badly or just quit. I would have spare plug on hand. Usually the first sign is that engine starts to act up, not idle, quits at half throttle almost consistently, won't even try to fire off, a variety of things.

Believe or not, the break in period is good for the driver, too. It slowly gets you used to the handling and other quirks of the rig. (that reminds me, watch your batteries; if they go low, the car could take off on you with no way for you to control it as you cannot communicate to it via the radio)

I worry about that every second...thats why I'm in a secluded area surronded by bushes! If it does take off, it'll just go into a bush.

Actually the first time we started it up, the throttle trim was at 3/4 throttle and it took off and tried to go somewhere and I paniced but then thought to get a towel and plug the exaust. I has that damn throttle trim...it's good to adjust Idol though. Thanks for the help and I can't wait till tomarrow to finish up break-in! :devious:

I used to stop my cars by plugging the exhaust, but then I realized that everything your engine produces from the time you plug it, till it stalls, gets stuck in the pipe. All I do now is pick up my car, and tap the flywheel with my shoe. The INSTANT stop method. Try it out next time

Nice job on the break in! Glad we could help!

Thats why you take off the glow plug and let the exese smoke BILLOW out...LOL. Now the question is after-run. I put ARO in all the places I'm supposed to, tried to clean everything up but theres a bunch of leaves in the bottem that I can't acess. I have an Air Compressor, but my dumb-ass dad broke it. So is there another way to get those hard-to-reach areas?
:hammer:

 

[Revo Rancher]

If it's just dried leaves I would leave it unless they are close to jamming something like a linkage. If there is a lot of them, if you have one of those cans of compressed air like for cleaning a computor keyboard, use that. Careful, as it can freeze parts. (I don't want to find out what that might do)

And, yeah, a little joke about your smoke. When you break in your mill a lot is going on, and a lot of weird build up is hitting the pipe and engine. Try the pinch method. Pinch the fuel line as close to the carb as you safely can. We will use this technique later on to determine if you are close to a performance tune anyhow, so get used to it.

In fact, I just ran my RB TM 323 powered Revo a bit in my garage and up the street to get it ready for tomorrow, and it was running like crap. When I went to pinch the line to stop the motor it ran another 10 seconds. Right away I knew what it was. Makes sense since the last time I ran it it was 80F out, and today it is maybe 60. Wayyyyyy too rich.

 

[SpitFireV12RR]

and tomorrow go break that sucker in and drive til your hands hurt......

I just though of this since my hands are in such pain:

Till my hands hurt from driving or from the pull start? :hammer:

 

[Monkey Wrench]

Man, why you gotta go crack on your Dad? Is he the same dumb-ass that bought the compressor? Seems to me that if he bought it, he can break it!

 

[SpitFireV12RR]

Actually, I gave him $40.00 so I could use it whenever I wanted and it was like $120 all thogther so it wasn't fair when he broke it and didn't fix it...

 

[Revo Rancher]

Good enough reason to complain, although, we don't know him and he might be the best dad in the world. Let's leave Dad out of it for now, ehh?!?!?

 

[SpitFireV12RR]

lol...he did lone me money to get a new fuel bottle, rechargable glow ignitor and an extra glow plug. SO I think I'll keep him...LOL!

If you can read this, you're too smart. Go to dumb schooL!

 

[SpitFireV12RR]

I just got two tanks full and it died on its own from fuel deprovation. I ran it a little harder these two tanks as you guys said to. I'm going to let it cool down and do my maintence because I don't want to run it again since I know the batteries in the reciever are almost dead. I could tell by the poopy steering and poor performance of the brake. It ran well, started on the 7 or 8 try on the first time and then the first on the second time. The only problem I had was when I gased it, it would stall. To keep it from stalling, you actually had to lift the rig, give it power for the wheels to start moving and then put it back down and it would go. Its probally just because of the richness. I'm still not going to lean it for another tank or so...just to be on the safe side and no offence to you Revo Rancher. Its become so fun to actually play with the car rather than think why it's not working. So I'm at about 4 Tanks now, can't remember...4 or 5 i know.

EDIT: Just put another about 1/2 tank through. Ran great, but its dirty! I'm going to let it cool and then put it up for the day. I ran it into the garage and could tell it was going to stall so I let it die, perfect timing! I started to get scared because the batteries were so low that it ran(moved forward, not idoling) when I didn't have the throttle on. I ran it on the street abit and attracted everybody on the block! Then when I went into the garage, they stood there as if I was going to refuel and come back out! LOL. I gotta get a hump pack and some rechargable NiMh for the controller.

 

[SpitFireV12RR]

Update: Just got another tank through with poor servo results(From low alkalines). I'd still be out there but its been giving me poor braking so I'm gonna stop till I get some new batteries(I'm gonna save up for rechargable NiMhs for the Controller and a hump pack). A temp gun is also on my list. It ran extremely well other than the servos and the speed was impressive(To a first timer). Still haven't opened it up all the way. I went to about 2/3 throttle slowly then applied the brake. I'm still a little scared to open it up as I don't have a fail-safe(yet) and don't want to go out of the radio range. It ran well, but it won't empty itself out. The tank still has a little bit of fuel in there. I'm sure this problem will stop once I mess with the carb.

Now I'm about 6 tanks through(maybe 5).

Going to lean it 1/8 of a turn next tank.

Oh ya. When I lean the carb 1/8 of a turn, do I do both the High and Low speed needles or just the high first?

 

[[email protected]]

are you sure it wasn't stalling because it was to lean and wasn't getting enough lubrication cause you have to have a stream of blue smoke coming from the exaust stinger either wise it cause premature wear on the piston/sleeve if i am not right idk i just started but make sure cause it is important it aint too lean

you shouldnt have to deal with the low speed unless it is taking more than 3 seconds durning the fuel line pinch to shut it off and like i said keep an eye on the leaning

 

[SpitFireV12RR]

No, theres an extremely visible line of smoke coming from the stinger, especially when I come out of a turn and accelerate!

 

[Monkey Wrench]

Only lean the HSN. I wouldn't mess with the LSN unless you have to.

 

[SpitFireV12RR]

I think I'm going to have to lean it later because if I let it idol for a minute or so to warm up, and give it just enough gas to start moving, it stalls, so I'm thinking it's too rich but it'll do for now. Revo Rancher...i'm going to start leaning the needle 1/8 of a turn as you said to do every tank(until it runs in optimal performance), any last-minute guidlines(actually it'll be awhile cause I need to get a temp. gun next time I get $20.00!

 

[Revo Rancher]

Todd:

Next time you run it (and you better get fresh batteries) turn the HSN needle clockwise 1/8th turn, go back and forth 40-50 feet in front of you goosing the throttle, and if it is still boggy or trying to stall, while it is still running, turn it in another 1/8. Do the same thing, run it back and forth.

What happens about now is that the engine is starting to run better and no longer likes the rich mixture, plus you are asking for it to do more because you are now giving it more and more throttle.

One sign that you have leaned it too much on the HSN is when you no longer leave a nice steady trail of blue smoke when you accelerate. Too much is bad, too, as that means you are too rich, but you should ALWAYS, even when fully performance tuned, leave a trail when accelerating.

Another sign you have gone too far with leaning the HSN is that the motor will now start to cut out or stall when you try to throttle past half throttle. It may even make a real boggy sound, like it is not getting any fuel.

Lets get the HSN dialed in a bit better and then we will work on the LSN. Many times just adjusting the HSN alone will get you to where you need to be, so lets do this in order. We'll do the pinch test after we try the HSN tune a couple of times.

 

[SpitFireV12RR]

Update(again)...I turned the High-speed 1/8 of a turn and focused on 3/4 throttle for this tank(only 1 today). It ran find and it seemed when getting in the higher RPMs to be slightly slowed down so I'm seeing that I need to focus on 3/4 right now. I gave it about 1 second blips to Full THrottle but it didn't really have enough time to speed up by the time I let off. Its not liking the rich mixture anymore but I'm going to run it at what they call(I guess) all most ready to race" setting. Then I'll tune it to scream. Its running great and I haven't had any problems but I'm pretty causous since I still can't afford new batteries(I'm actually saving up for rechargable NiMhs(AAs) for the controller and a Hump pack for the Rx.) I haven't really cleaned it fully, but it really doesn't need it...just a leaf or two at the bottem and a little bit of dirt here and there...nothing really. I'm glad I got into this hobby...especially this forum(It sure as hell beats the retards at RCU!)

P.S. Hey 4u2nv...can I get a decal in the form of the picture of your signiture? :bling:

 

[Revo Rancher]

Todd, is it losing power and trying to dump rpm when you let it really rev (on the ground) and/or giving it full throttle? If it is, stop with the HSN turns.

Then, next time you run it, once it is fully warmed up after a couple of passes, pull up to yuo close, pull off the body, and pinch the fuel line about 1-2 inches from the carb and hang on to your pinch until the motor quits. Make sure you have a good hold of the wing with the other hand as the motor will rev quite a bit usually just before it quits. While pinching the line, count, "one-alligator, two-alligator..." and then report the results. If you get over 5 'gators as a result (still count past 5 no matter what until it quits) we will start doing something different as far as a final tune.

No...it sort-of hesitates. I'm think part of it is the bad batteries. I did the [Line pinching] thing, and I got about 1-1/2 aligators. Is this bad? :shrug: I

I do have one question. The car, when at about 1/4 ish throttle is going good, but it sorta sounds rough, as if it is under alot of load. It usually sounds this way when taking off. It's sorta sluggish then out of no-where starts to take off at about 1/3 throttle. I'm thinking after I get the high-speed taken care of, I need to adjust the low speed.
