    Richen your carburator you are running way to lean if you don't change it you will blow the motor. If that is the problem it isnt good so richen it and watch it. If after about two tanks of gas and there isnt any go to your local hobby shop. it will tell you how to change the carburator in your manual.

    Just a suggestion. Before you start asking hundreds of questions, READ YOUR MANUAL, AND OVER AND OVER. Then maybe get a few mazagnes or research nitro cars on the internet to get an idea of how they work and how to use them properly.

    There are lots of R/C car magazines available in the UK and some originate there as well. I suggest you contact a local R/C car club and solicate help directly.

    There should be some smoke visible ehwn you run a 2 stroke motor such as the one in your vehicle. If you are running yours and do not see any smoke then you have the carb set too lean. This means the motor is not getting enough nitro fuel and too much air. Your carb should at least have one needle valve that you can adjust. Turning this needle valve counter clockwise will richen (add fuel) to your motor while turning it clockwise will lean (less fuel) the motor. Too lean will cause over heating problems and you may end up causing damage.

    2 stroke motors use a "total loss" oiling system so running too lean is not good. By total loss, I mean that the insides of your nitro motor are lubricated by the oil contained in the fuel. Each time your motor ingests, burns and expells the fuel it lubes the insides.

    Go to www.nitrorc.com and read up on how to run your nitro vehicle there. They have a nice article on tuning your motor and also have a forum dedicated to running nitro vehicles.

    Nitro motors do not just switch on so you'll need to explain your situation better.

    OK.....I assume you use either a pull-start or use a starter box to get your nitro car running. The clutch will engage and cause the wheels to turn it if manages to rev high enough. If this is happening, then you have the throttle open too much. You should be able to start your car and have it idle without the wheels turning.

    Remove your carb air cleaner and with the throttle trigger on your radio at idle look to see how open the carb actually is. There should only be a tiny opening visible. If you see more, then adjust accordingly and close it a bit.

    To set the carb up I would do the following;

    1) Turn on your transmitter and leave the trigger (or throttle stick) at your normal neutral setting
    2) Turn on the receiver battery pack in the car
    3) Remove the foam or paper air cleaner that sits on top of your carb
    4) Looking down into the carb, adjust the linkage from the throttle servo to the carb so that the barrel inside the carb opening is a few milimeters from being completely closed.
    5) But the air cleaner back on the carb
    6) Use a new glow plug if you have one and try again.

    I recommend you use fuel designed for R/C cars only. Something with 20% nitro is fine. When I ran nitro boats I used Byron 25% nitro fuel and always added one ounce of Sig AA castor oil to every gallon. I did this to ensure that my motors received enough oil to make them last.

    Is that 16% nitro or 16% oil content?
