question about break in. (noob)

[Socomgod 420]

whats up guys, I have a duratrax warhead evo. Right now I'm doing the "heat cycle" as suggested in the guide for beginers sticky thread. I just finished my 3rd heat cycle and everything seems fine. However if i pick the truck up and apply any gas (barely opening the throttle) it dies.

any ideas?

also there is a decent amount of fuel coming out of the exaust pipe. I'm assuming this is normal for a engine running rich right?

I have the hsn set to what duratrax recomends for breakin.

edit.

now I've done the heat cycle about 6 times now. the truck starts just fine, it seems to have no problem idling either. its just that when i give it gas it just dies instantly. I havent touched the hsn yet. Duratrax break in video acts like it should run just fine as soon as you start the truck.

Someone pleas help me out. thanks in advance.

Shane if you can't help don't reply ok!

Do what jet said lean out the hsn..try 1/16 of a turn at a time...Run for about a 1/4 tank and lean it some more...In till you hit that sweet spot.

 

[Socomgod 420]

Lean it out slightly, it's too rich

ok I will try. What really sucks is that it just started sprinkling so Even if I do get it running correctly I can't even drive it right now. Will it hurt anything if I can't finish the breakin today? If it doesn't stop sprinkling and I have to put the truck up should I just let it idle until it runs out of fuel? duratrax recomends not letting the fuel tank run completly dry until you are finished with the break in which they say should take 5 full tanks.

please someone let me know, I dont want to screw the truck up before I even get to enjoy it.

**edit**

ok I just tried leaning it 1/12th of a turn. still getting the same results. should I just keep leaning it until it will accelerate without dying?

God I hope I didnt screw the truck up somehow.

Start it and pinch the fule line intill it dies..
If your going to run itin the next few days it will be fine...If it sets for any longer add a few drops of after run oil down the plug hole.

yes turn it a bit more...Do you have a temp gun?

Not yet. I've already spent over $500 on this thing and accessories. I didnt really want to spend more on something I didnt absolutely need.

Thank you very much for your help though.

A temp gun is a great thing to have, but you should not need it. I would recommend it, though. Duratrax makes a fairly decent/cheap one that can be gotten around $30. First, check your needles are set correctly by looking in the manual for the factory settings. From there, you can always lean it down.

Zandors suggestion of pinching the line is a great one, but once it dies, pull the line off (while still pinching it), then drain the tank... Re-attach the line, and re-start until it's dry.

"Pausing" the break in shouldn't hurt the motor; I've got a couple motors that I've done that to (an extended break-in, if you will), and they run just fine.

Also, have you tried leaning the low end needle about 1/8th of a turn?

I havent messed with the lsn yet. duratrax instructions say that you shouldnt touch the lsn until the engine is broke in.

When you say re-start it until its dry do you mean actually start the engine (using glo starter) or just turn the engine over?

I've always ran electric in the past. I dont know anything about nitros yet.

Thanks for your help.

also I checked the adjustmen for the hsn. I made sure that it was at 4 1/2 turns out.

I have to drop my little cousin off at work so I will be right back. Once again thanks to everyone who is helping me right now.

If you have the engine broken in, start it, bring it up to running temp. around 200 f. it helps if you have a heat gun or on bord temp monitor.start buy leaning it out in 1/16 turn or 1/8 turn. run it down the street. takes a minute for the adjustments to work,repeat this till you find the sweet spot check temps. should be running around 220 to 250 range, nice streem of smoke, remeber and adjustment on the carb will take a minet to set in.

the only thing I've done so far for breaking in is the heat cycle which I've done 6 times so far. I'm gonna keep messing with the hsn until it will accelorate without dying.

Just keep leaning it out slowly youll get it, remeber any adjustmet take a minet to kick in, it should accelertate with out dieing,nice smoke streem, you can allways check the temp buy spitting in the head should take about 5 sec to fizzl off any faster it might be getting hot. sounds stone age but works if you dont have a moniter. If you dont have a heat monitor get 1 really help's and can save your motor from overheating and tosting it. hope it helps have funn.

ok so i leaned the hsn another 1/12th of a turn started the truck let it idle for a mnuite then tried applying gas and the same thing keeps happening. It just dies as soon as any amount of gas is given How much is to much to lean the engine? cause duratrax break in instructions say that you should only have to lean the hsn 1/12 of a time a total of 4 times. 1/12th of a turn after each tank 5 tanks in total. I'm on my 3rd 1/12th lean and i still can't get it to move.

I wish my lhs was open right now. I would just take it up there and let them help me.

this sucks.

just tried again with another 1/12th lean. same thing. I did notice that fuel isnt coming out of the exaust anymore. Is there an adjustment on my radio that I need to mess with?

Here is a link to the manual.

http://manuals.hobbico.com/dtx/dtxd69-manual.pdf
I dont know what to do at this point. I feel like i wasted $500.

OK do this lean it 1/8 of a turn more....And run it..be smooth on the throtle...Bring it back to you and take some spit on your finger and touch the head..The spit should evaporate over about a 2/3 sec.time...If it just sizzles off it is running to hot...
in that case you will need to turn the hsn the other way...
I don't think this is the case but try it and let us know.

as soon as I give it any gas at all even while holding the truck off the ground the engine just dies instantly. I'm afraid to lean it anymore cause I'm afraid I might really mess it up. on the duratrax dvd and instruction manual they act like the truck should run roughly on the first tank with the hsn set at 4 1/2 turns which is factory preset and what they recomend for the first tank. It mentions nothing in the break in procedure about the problem I'm having.

also should there be blue smoke even when the engine is just idling? cause even with the hsn set at the factory break in setting I'm not getting blue smoke while its idling. I did notice however that when i shut the engine off by clamping the fuel line that the engine would rev up for maybe 3 or 4 seconds. while this was happening there was visible blue smoke.

could it be something to do with the radio. there is a switch for steering reverse and throttle reverse. they are both set to normal. Also I havent messed with the throttle trim at all yet.

Will you look over the manual i posted and see If its something that I'm just obviously missing.

I'm not new to rc just new to nitro. Starting to wish I would have just fixed up my kyosho laser.

I have a feeling that its something really dumb that I'm doing or I'm hoping so.

Once again thanks for all the help guys.

All right do this..Turn your LSN in 1/8 of a turn..
befor you start it...Fire it up and try to run it..
Factory settings are only that..Some time you need to make small adjustments from there settings..Try it and come on back.
We will get you there trust me.
i am sure others will chime in also.

why do I say lean out the lsn? Because your pinch test...Sounds like your lsn is a tad rich.
2/3 sec it should die..3/4 or 5 is to much.

ok so i leaned the lsn a lil more and it worked. I'm gonna go run a tank real quick. Ill let you guys know how it went. once again thanks.


ok a
fter leaning the lsn the truck started then it just died while idling about 10 secs later. Now it doesn't want to start. However I noticed that if I hold the glow plug igniter it will run but as soon as i take the ignitor off it just dies. does this mean that the plug is worn out?

I just pulled the plug out and checked it. IT appears to be fine. Its glowing orange when its hooked up to the ingitor. Is what I described above the engine flooding??? doesn't make sense to me.

i ran through the first tank with no problems. I tried to take it very easy on her. never got above half throttle. Its still running rich which I guess is a good thing since I'm still breaking her in.

I accidently let it run out of gas and had to go shut it off. Then I filled up a second tank. I went to accelorate slowly then all of a sudden the steering and gas were not responding. The truck took off going maybe 10-12mph and slammed into a curb. I ran to it and pinched the gas line. the batteries are brand new and i just put them in today. It was dark so i just packed it up and came home. I hope I didnt damage it in any way.

Now its sitting here with a full tank of gas. What should I do with it? drain all the fuel and throw it away or what. I work a 12 hour shift tomorrow so I probably wont be running it tomorrow. Will It be ok till tuesday? or should i drain it?

Once again thanks to everyone who helped me today. I was ready to just give up.
