Can be anything!

- wrong TH trim setting on the transmitter (most common error by beginners by just touching it or after a crash and so a light bend chassis)
- A high idle setting
- A too lean LSN
- a bad servo.

First thing I picture is that your 'off throttle' position doesn't actually hold carb slide to 'closed position'.
Take off air filter and check the 'on throttle'...'off throttle' positions. Might be a simple 'trim' setting or need to reset 'neutral' on servo arm.
Off throttle move to adding 'go' should be definite move off idle screw 'rest' position where you've got the prescribed 'air gap' to let motor start and idle.

Does it drive forward immediately, or does it take a few seconds after starting before it begins to drive forward? If it takes a few seconds, then it sounds like your LSN is slightly too lean. If it drives forward immediately, either your clutch is malfunctioning or the idle is set too high. (if you can't get it to idle stably without stalling, then it's the clutch, not the idle setting.)
