Hi all new member here name's Cort, Ihave a quick qustion i have a revo with os.21tm in and it runs awsome starts right up brand new engine plenty of smoke shifts on time only problem is is once i hit let it idle for 4 seconds or hit the breaks to hard after a high speed run it dies any ideas on what could be causing this? Icheck the carb with the engine off and the breaks didn't close the carb so

During the idle, what's it doing?

1/ If it is gradually slowing down and dies, the LSN may be too rich.

2/ If it gradually speeds up and dies, the LSN may be too lean.

Since it dies when letting off the throttle as well, I'd guess #2.....the LSN may be too lean.

These arn't the only reasons, but it's a start. Your HSN may be too lean and that's all there is to it, but I'd start with observing the idle as above.

you might need to raise the idle via the idle screw .

ya id check the idle first, try giving the idle screw either half a turn, or maybe a whole turn

Thanks for all the responces guys I think i've got it setttled for now she's running pretty good
