This is extremely dumb to most of you

[vbgagnon]

sounds lean on the bottom to me. Give it a 1/8 turn, you want to have 3-4 seconds before it dies. But remember only do this when the engine is at operating temps, otherwise it is not accurate.

 

[SpitFireV12RR]

It may be, but there is still a shitload of smoke from the stinger and its actually only 1/8 of a turn down from stock settings!

 

[Revo Rancher]

Todd, glad we did this. It sounds like we may have gone too far on the HSN. Turn the HSN 1/8th to the left or counterclockwise and when you get fresh batteries, try 3/4 to full throttle to see if it is stops the problem.

Also do the pinch test one more time after you make the adjustment.

Just so you know, absent a heat gauge, the pinch test will tell you you if you are too lean. Right now, you are too lean. I suspected that because you cannot get full throttle. What has happened is that we leaned the HSN so much that ALL fuel getting to the carb has been so reduced that with the heavier demand of fuel needed for full throttle, it simply is not there and the engine therefore leans out. We will add a bit more to the HSN until the pinch test gets us to 5-6 seconds or more and then maybe barely lean out the LSN to see if the low end cleans up. From your last description, it sounds like the top end leans out (and too much with more and more throttle) and the low end still loads up.

 

[vbgagnon]

If your dying at 1-2 seconds and will idle for a minute to me that is lean. My stuff won't idle for a minute with out loading up big time. Do you have a temp gun? I would definatly look into getting one.

 

[Monkey Wrench]

Just a suggestion (and mind you, this is simply my personal opinion), I'd save up to get the hump pack for the RX, then get yourself a temp. gun. Rechargeable batteries for the TX can come later. Most TX's that I know use 8 "AA" batteries, and you can go a month or two on a set (from my personal experience).

Are you looking for a 5-cell hump pack? I may have one I can sell cheap, but you'd need to get a charger. Let me know.

 

[Revo Rancher]

Yeah, on edit, I looked back and noticed his comment about the car finding power and smoothing out after it got half throttle, but he had fiddled with the LSN without telling us before.

Todd, I did not know you fiddled with the LSN. This changes things. Like VB says, add back any of the changes you made to the LSN. You are too lean overall and definitely on the low needle. After you move it back or even a bit more try the pinch test. If your acceleration on the low end gets better but the pinch test still too short of time, we'll add a bit more to the LSN.

 

[SpitFireV12RR]

Actually the dude at the LHS leaned the HSN needle about 1/2 a turn to actually get the thing started. I didn't think I should lean it much more than he did. I will put the HSN back about 1/8 of a turn if I'm understanding you guys and then put the LSN back to stock settings(which is flush with the sleeve.). My car will idle for quite a long time(2 or 3 minutes then it gets loaded up and I"m too unpatient to let it idle that long anyways.). Monkey Wrench, if you are willing to put it on ebay(you can always cancle the auction once I bid), I can buy the Rx pack(I'd like some pictures of it though and history, ect) The reason I can't buy it from you unless it's on ebay is because of my parents(not that I don't trust you).

I'm gonna go reset the needle. I guess I should tell everyone everything.

Maybe a movie would help? I have acess to a Video Camera, I just need to get my dad to hold it.

 

[vbgagnon]

2-3 min imo is WAY too long. Richen up that lsn, your looking to get 3-5 seconds on the pinch test. If you have that you will be very close on your lsn setting.

 

[Revo Rancher]

Todd, all along I have been telling you to lean the HSN. If you instead have been leaning the LSN, then get that back to the factory settings and get some new batteries, then we'll talk. It's good that you got it running, but hey, let's face it, we almost have to start from scratch here because you did not listen.

And do not move the HSN either direction until we have the LSN back to factory settings. It might be where it should be, or at least for now. Your rig runs, so that is a sign it is breaking in and the needles are not out of whack.

 

[SpitFireV12RR]

I've been leaning the HSN. The one in the brass sleave, correct? This one(A):

I do think the LHS messed with the LSN though...it was way in from factory and I haven't touched it(It was about 1/2 turn in from full which was WAY to lean. I'm supprised the LHS did it that far.

I returned B to stock settings. I have never touched the LSN, halfly because everything I've read says to adjust the HSN first, then focus on the LSN. I'm going to do the pinch test tomarrow(Its dark here on the east coast). 3-5 seconds...I'll look for that after I warmed it up. Its never cut out on me though, just a little sluggish in low speed, like I said at about 1/3 - 1/2 if takes off.

 

[Revo Rancher]

OK, you have the needles correctly identified. "C" is your idle screw. Leave that alone.

See in the photo how the LSN is flush with the case? Make yours look like that if you cannot find the factory settings anywhere. Leave the HSN alone.

THat actually is factory...flush. FLush means if you run your finger by it, you can't feel any diffrence(like it feels flat all the way across)

 

[vbgagnon]

Give it a 1/8 turn rich. try that. It sounds really lean to me.

I returned it to stock...which was about 2 turns out which was scary!

 

[vbgagnon]

2 turns out or 2 turns in. Lean is in (tight) rich is out (loose)

 

[SpitFireV12RR]

2 turns in(Took me two turns out to get it back to factory.). So yea, the LHS guy had the LSN way too lean when he adjusted it.

 

[Monkey Wrench]

SpitFire, I'm not going to go through the process of establishing an eBay sale for a $10.00 hump pack, it's not worth it on my end, but I am glad to see your parents are putting controls on what you can buy off the net.

Keep following the advice Rancher and VB are giving you. Two guys that truly know what they're talking about. They won't lead you astray and that rig will run for many moons!

 

[SpitFireV12RR]

Okay. I warmed it up today and it's really windy and cold down here(Were supposed to get down to 32 - in Florida, tonight!) and I let it idol about 1/2 a minute, and took off. I did a few passes and brought it in. I pinched to fuel line about 1 1/4 inch away from the carb. It idoled, speed up, and then cut off, all in about 3 Al-I-Ga-tor. Then I started it up and did a few more passes. I brought it in, did the same thing...it idoled, speed up, and then cut off, all in about 4 Al-I-Gators...BUT!! I pinched it about 2 inches from the carb. I just wanted to see if the motor cared and it did. I fliped it today and got a scuff on the heatsink of the engine...no biggie(I'm becomming a speed demon, especially when it's turning :devious: ).

I returned the low-speed needle back to stock...and it hesitates now. It doesn't make the ling-ling-ling(then more throttle) rrrrrrr. It makes a hesitate then RRRRRrrrrr. I may want to lean what now?

I know I'm becoming a PITA and I greatly appreciate everyone for helping me, especially Revo Rancher as he's helped me through all 6 pages!\

Thanks everyone,
Todd

Is it really really sluggish? If not I would leave it were it is. Just for protection, until you get it really good and broken in. Glad we got it figured out.

If it is really really sluggish I would lean it 1/8 of a turn and try it, if still too sluggish repeat. remember the lsn is a very touchy needle, moreso then the hsn. Very small increments will do a lot.

 

[Revo Rancher]

Yes, where you pinch it will make a difference, therefore, it is important to always pinch it at the same place for consistent comparisons.

At this point, I would lean the LSN 1/16 (it seemed to like the LSN a little lean) and richen the HSN by about 1/8. Your bogginess on the low end should be better and overall you should be richer, protecting your engine. If it runs decent there and still gives a good smoke trail when accelerating, stay ther until you get a temp gun. Still occasionally check it by the pinch method to see if the tune has changed.

Another reason it may be running a bit different today is that the weather changed, so let's not adjust too much today. Your weather should get back to normal in a couple of days so why retune it twice.

On edit;

VB beat me to it, but it looks like we were both thinking the same thing about leaning and leaving it for awhile.
