I hope I can get this fixed today. I'm having trouble starting my T-Maxx. The engine it hums at the idle speed then when I let go of the button the engine stalls. If I accelerate I might be able to get it going but then it cuts out. I just pot in a new spark plug and a new break survo. I increased the idle speed thinking it was that no luck. Anyone have an idea?

hmmm.... not completely sure but i had the problem once before. what i did is richened the fuel mixture about 1/4 of the way around until i finally got it after i did about 2 full turns. in short, when that happened to me it was way too lean.

You may have the LSN set too rich. A lean setting of the LSN will cause a high-idle condition that you won't correct with the idle set screw.

If your engine starts but it won't idle it's usually one of two things. Idle screw or LSN. Your idle screw should be set so the gap between the slide and the carb neck is about one millimeter.

The factory setting for the LSN is where the screw head is flush with the inner lip of the housing.

Factory setting for HSN is clockwise to seat, then out four full turns.

And we'll ignore the attachment. Go easy on the smileys.

Hey just to tell you something please spell right to make your thread easier to read plus it is a rule: Quote,Use good grammar and spelling - If English isn't your native language then please say so. Otherwise its very annoying and hard to read TeXt THat LoOkS LIkE ThIS. This isn't a spelling bee, but please try your best at spelling.

But only hold half throtle when you are tring to start and maybe your glow plug is bad. Buy a new glowplug. Also put the needle settings back to factory.
 
One i"m ld in splelling thank you. two i said i just bought a new god for sacen glow plug. So partern me if I'm not perfict damit. How cares about the f@#$ing spelling. I mean what are you a english teacher.Hey wdavidhicks i agrey with you. That also what the guys at the hobby hanger (our hobby store in suly plaza In herndon VA) are telling me. Also i could be that it is about 26* out.

sorry about the smilles. the deadly arent they.
 
i doubt its the temp unless it was sitting ou there for a while b4 you tired starting it be cause i was bashing mine in 10F today and ran REALLY good surprisingly since the highest temp it got to was 190
 
Just a thought, but is your clutch dragging? I know when the spring gets weak or broken, the clutch shoes constantly drag which causes idling issues. It causes other issues as well, but not idling is one of them. Or if your clutchbell bearings are shot, will cause the same sort of thing.
 
If you pull off your air filter and look in the carb at the barrel with the remote and receiver on, you should have a 1mm-2mm gap at the end for idling. If you don't have this, your throttle screw is to far out.

I know this is basic, but no one has asked yet.
 
i see. ...... It isn't that

defently isn't that

but i will try
 
it ge to the humming idle speed sound and i hold it there but stops when i turn of the e-z start.
 
Have you tried an external glow plug heater? The ez start doesn't allow you to leave the plug hot manually. I find it's way easier to keep it running when it's cold out if i leave the heater on the plug for about 10 seconds after it starts running.

I don't run the stock maxx anymore, but this rule still applies to any nitro engine. Or, at least it should.

Using an external glow heater also gives you much more consistant starting.
 
I'm still tryin to figure out what this guy is talking about... so much missed spelled words... I'm so confused.

throghtale survo?? throttle servo?

later
 
jerk i have a spelling problem let me be

Easy there chief.... It's a little hard to understand what your talking about when there are so many mispelled words.....
Do yourself a favor, and try using a spell check. Maybe more members will try to help ya out....
 
This happened to my sportmaxx. if it keeps happening , return the needles to stock, and lean out the lowspeed 1/4 turn. and also let your engine warm up before trying to gas it or drive. Good luck!:thumbup:
 
Alrighty then.

You have replaced the glo-plug. News flash, glo-plugs can burn up on one start or after a year of starts. It is not beyond reality to recommend that you check the plug.

The needle settings have been hit on a couple of times and the idle setting (1mm gap) has already been addressed twice.

If the temps are as cold in Herndon as I have read about, that adds to the fun of trying to start the engine. Using the EZ start without a separate glo-ignitor is also going to add to the fun of starting an engine on a really cold day.

The best thing you can do:
1. Reset the idle set screw so that you have a gap in the carb when the throttle is closed. That gap should be about the thickness of a credit card (1-2mm).
2. Reset the engine's needles (HSN and LSN) to factory presets.
3. Get the hair dryer or heat gun out. When you try to start the engine, give the engine about two minutes of time with the hair dryer blowing on it. This should heat the engine block and head up sufficiently.
4. Make certain you prime the engine and then give it a go. If the EZ Start still does not start the engine up for you, I recommend investing in a separte glo-ignitor. After you have one, then try steps one through three (above) again. If the engine still doesn't start, there might be a bigger problem.

As a side bar, the best way to get people to help you is:
1. Work on the spelling. Posts that are difficult to read do not encourage others to help.
2. Learn to take constructive criticism. Regardless of your spelling abilities, flying off the handle when someone points out the deficiency only causes people to ignore you or respond in kind. If you have some kind of limiting disability that is the root cause of the spelling issue, let us know that and we will leave you be. Otherwise, make your best effort to spell properly and remain calm.
