This did not happen when it was colder, it ran great.. Now that it warm, I cant keep the thing running.. Iget it started and it runs,, but as soon as i let of the gas to much it stalls.. Then it gives me a hell of a time starting and stalls as soon as i left off the gas.. eventually I cant even get it started..

Ihave messed with the tune.. Ieven went back to factor setting and started again.. I cant get it to stop stalling..

Anyone could give me some idea what it may be or what I should be trying to tune it to.. richer/leaner.

turn on your reciver and transmitter but leave the engine off, take off the air filter and make sure there is a 1mm opening in the crab. that should do the job, put your air filter on prime the engine make sure the glow plug works and your good to go

Dads like rc too

First off you were right to retune with your temp shift. When it gets warmer you engine runs more rich. It could have been so rich that giving it throttle was flooding it and stalling. But since you've checked that, what your describing sounds like a bad clutch spring to me. When the clutch spring is bad, the shoes are constantly engaged in the clutch bell making it harder to start. Also it will usually run fine when free wheeling like if you had it sitting on a box, or when throttle is applied. But when you take it off the box and it immediately stalls when the wheels touch the ground, the clutch stalls the engine.
