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.

Poor casting ability


Remove the left side plate and set the little plastic things ( I think they are yellow) so they are against the inside..they should kinda snap inwards and stay there...
Found a video ( not well made but it shows how to access the brake system).. you will see the SIX little yellow plastic brake adjusters... start with moving FOUR (4) - opposites of each other - of them inwards towards the spool shaft.. they should "click" inwards and stay there...CAST carefully the next time.

MY PRIDE REVO MOBILITY SCOOTER IS 3 YEARS OLD AND IS STARTING TO HAVE A INTERMITTENT FAULT OF GOING SLOW AND THEN FAST LIKE HAVE DIRTY PETROL IN A CARBURETTER IN A CAR


I know what the problem is as I have had it no less than 3 times with my own Revo. The Throttle Pot needs replacing. Luckily they aren't very expensive and you can fit it yourself if you are a handy sort of person. It just involves turning a screw to take out the old one and put in a new one. You can find diagrams on how to do it on the Internet. If you call a mobility company to come out and do it for you, they usually charge about £50 as a Call Out Fee.

The Revos seem prone to this throttle pot problem. Hope you get it fixed soon.

Traxxas revo 3.3 running problems


Maybe running to lean or to rich. When you accelerate put youre hand where the exhaust is and you should get a light spraying of unburnt fuel over hands(lovely!). If you do you may be able to screw in high end needle in a bit and i mean just a bit. If you hear the engine note raise a bit with a slightly higher pitch then you are running to lean and you will want to unscrew the high end needle valve asap.
Also check youre idle screw and make sure thats not closing the carb and stopping any airflow into engine. Let me know how it goes.

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


Hi
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
