Check that your fuel tank is fully sealed as fuel is pumped through it via exhaust pressure, other wise check the fuel lines/carby aren't blocked. You may also have too much fuel, as it would build up and stall your car in a few seconds. Try a pinch test: start car then pinch the fuel line near the carby, if it revs a fair bit harder then stops- could be to rich, if it doesn't rev any different before it stops it's too lean and needs more fuel.

Got a traxxas 2.5 i think? Been around plains for years and can tune them fine but for some reason i cant get the truck tuned. Starts fine cold but when running hard smoke goes away and starts to bog....

Sounds like the high end needle might be too lean. Have you checked the engine temp while running. Traxxas engines usually like to run around 210-240 degrees.

When i start my truck the motor starts to REV very high and wont go i can see the gear spin at the bottom but think maybe something is not catching up top. last time i drove it was fine it did REV up...

you have two different problems. The engine is reving high because fuel into the engine is being starved i.e. the fast idle is set too high. This can eventually lead to a ruined engine. Traxxas engines are designed to run very rich with a heavy amount of oil to keep them cool. Retune your engine. Secondly your clutch shoes have probably glazed over or are simply worn out. Replace these. There's alsways a possibility that you've broken a gear in the transmission but the clutch shoes are much easier to replace and probably should be at regular intervals. Your manual will explain how to change them and how to retune. Good luck

Revo 3.3...engine doesnt stay on...

Could be a couple of things. Firstly the glow plug may need changing or youre running slightly rich. If you was replacing the glow plug you should retune the engine anyway. When the fuel is entering in the engine where the glow plug is theres either to much fuel and flooding plug out or the plug is not up to the job of burning the fuel. Replace plug and retune. You have had car for two years so guessing you know how to tune the engine.

3.3 revo hard to start after started it will not idle and when it dies it does not want to restart. This did not happen until I drve it thru alot of wet grass last year

2 stroke engines are very simple. If there's fuel (under pressure) and a spark it will run. Check the glow plug by trying to start it with glow plug removed but still connected and touching the engine body. If the little center wire glows bright red, then it's OK. Only do this for a second or so. If the plug is OK then it has to be a fuel problem. Traxxas has a long history of cracked gas tanks. Good luck

Problems with RC engine not running right!

Theres a idle screw located on engine under airfilter, should be small flat head. Clockwise will stop the carb from closing thus not cutting engine of. Also make sure you run car slightly richer than leaner. Hope this helps.

Nitro car wont start?

Motor could be damaged from getting too hot. I would try to reset carb settings back to neutral from the factory. The manual that came with the car should tell you how many turns out they should be. Also check the fuel lines to make sure they did not get damaged. Nitro motors normally run best at 210 - 240 degrees. Much more than 240 degrees can damage the motor. It is always better to run a little rich than lean.

Nitro engines can be difficult to start and keep running unless they are in perfect tune. This take quite a bit of experience, even the experts have difficulties sometimes Go to for web help. Or go to your local hobby shop and ask for help.
