I am trying to tune my Jato for racing on sunday. Here is the problem-every time i try to go full throttle the engine sputters and then stalls. This also happens when i try to gradually go to full throttle. But it runs fine at half and 3/4 throttle. Any ideas on how i can get this to run right?

Try leaning out the highspeed needle 1/8 of a turn and see if it makes a difference.

Depending on the sputter sounds it could be rich or lean. hows the acceleration up until it dies is it good or is it bad. Im thinking that it could be rich but im also leaning towards lean. Just try richening the HSN up a bit a if it helps keep on doing it till it gets to the performance you like. Or if it just makes it worse try leaning it out then. It is aslways better to be rich then lean so Thats why I said to richen it up first.

It is deffinently lean If it where rich it would bog an die since it is lean it revs up sputters and dies... IMO

I fixed it. My high speed was to lean, now i can go full throttle.

Just so everyone knows, always richen first. If it gets worse than lean it out.
