I have just broken in my engine on my new T-Maxx but when I was on my 5th tank it kept dying after I applied the brake and let it idle for a few seconds. I have tampered with the idle screw but this has done nothing. After the engine stalls it wont start back up until i wait for 15 seconds or so. Any ideas?

I also have another question. What needs to be done in order to aquire crisp off the line accelaration because right now i can't get the front wheels of the ground?

Well, it sorta depends on the temp there.

you need to tune for the weather, if its really cold then lean it out because the air is more dense

if its hot (highly doubt it) then richen because the air is less dense.

I would first juggest to get a temp gun. I have found that when my jato did that the temp was kinda high. once you get the HSN set then you can set the LSN and idel. The lsn will make a big differance when you first hit the gas. Then manual tell you how to set it.

This is wrong!!!!!!!!

Cold air IS denser and that means it has more oxy which means it will run leaner which means that you should RICHEN up the engine
Warm air is less dense so there is less oxy which means you need to lean it a little bit.
Again:
Cold=dense=lean=richen.
Warm/hot/humid=less dense=rich=lean it out.

Jeeze, I wish people would quit posting stuff that they don't know about.

no he's not wrong!!!. when the weather is hot your engine will run hotter and in order to cool it down you need to richen it up and when the weather is cold the engine will run colder and in order to get the temp's up in the engine you need to lean it out. i've been doing this for about 5yrs and race with guys that have been doing it for 10-15yrs and they all say the same thing.

i got to agree with DaveG55 about how when its colder you richen your engine and when its hotter you lean it-i still dont understand how often i come across people posting the opposite

about getting a crisper take of and your engine dying after you let go its your lsn
sometimes people make the mistake of turning in the idle screw to keep the idle up
when your lsn is to rich your engine is real slugish and it will stall right after you let go of throttle
you then need to lean your lsn-try the pinch test it seems to work really well

dave is correct the more oxygen the more fuel is required to run correctly

people that lean it out to get temps up in the cold are ruining there engine because all they are doing is running the engine extremely lean to get to there desired temperature.

how do i over come this they say?......................easy simply wrap a neck of a scok around your cooling head or wrap a paper towel round it

Yes, he IS WRONG!!!!!!!!!
I don't particularly care what you or your "racing" buddies do to your engines but you should stop giving advice that DIRECTLY CONTRIDICTS what Traxxas advises.
Look about 3 sections down in this article.

But, hey, what do you care, it's not your warranty your screwing up!

Dave is wrong, any simple Mechanic can tell you that, When its cold you Lean it out, When its hot you Richen it. Get your facts straight before you try to prove someone wrong. And I just read your new post Dave its Bogus its not true. Belive me I race real Cars and It is the same principle for the lil guys. Please dont try to contest cuz frankly you wont win nor does anyone care, The guy has a problem and we will help. Whats with all this man vs man Hate goin on here?

your right, both of you, you can only lean the engine out so much, but you do want to lean it out, but you ALSO minght have to wrap the head to get temps up too. if you usually run it at lets say 75* out, and now its around 0*, you dont want to lean it out that much.

okay read ur freakin manual. From racing I can tell u that when it gets colder between races I richen a 1/4th turn. it comes off the same temp cause when the air is colder it has more oxygen molecules pure air so u need more fuel. I used to think it was the other way around but when I got a .21 motor it came true to richen when it gets colder. and lean to a point when hotter. but this mostly pertains to weather in the 0-50 degree.

Well when My engine runs awsome in the summer and yours guys blow up from over heating dont blame anyone but yourselves. I race and build cars so I think I might know what Im talking about

but i have also blew up a nitro engine by tring to lean it out enough just to get it over 200* here, so thats why i do both, and mine runs fine, i ahve 3 gallons on my 2.5 and its still running strong, this is its 2nd winter.

Here is a direct quote from Traxxas. It comes from the link I posted above.

"After the engine is running, it is important to keep the temperature of the engine up around 200 to 215 degrees during break-in. In weather below 45 degrees, the TRX2.5 engine will not want to run over 160 to 180 degrees (when tuned at proper break-n mixture settings). This is too cool for break-in. Do not lean the engine to get a hotter temperature. This will decrease lubrication as well, and will also cause your piston/sleeve to wear prematurely.

You all can make up your own minds. Believe the engineers that designed and built the motor or some guy that "says" he "builds" cars. It's your choice. I'm done.

Thats during break in you need the oil to lubracate the piston and sleeve during break in. Im not talking about that, He already broke his vehicle in. Hes after the fifth. Im not calling you stupid or nothing Im stating a fact

But you still need oil. If you run it lean, you will have less oil, and the engine will run hotter. Running hotter means more friction. Don't you need oil to reduce friction? You don't want the engine to run lean at all. It is better to be rich, than lean, but ideally, you still want to be just slightly rich. Don't forget that that piston in your engine is aluminum, and it doesn't take much to damage such a soft metal.

simple as this:
hot out--> lean it
cold out--> richen it

if you dont believe me read your book, if you still dont, ill scan it in for you so you wont screw other ppl up

jettman listen to moore he is right you can only lean it so far without damaging the engine if you lean it and it still is not at the temp you want, then you put a sock or a towel on it to get it up in temps. cold weather is like having to big of a cooling head on your engine it is never going to get up to temperature.

i like tin foil, just put a few layers and then you can add or remove them really easily
