I have a Reedy 121 motor I have run about almost half a gallon in...It idles wonderful and when you bump the throttle it runs perfect but when you come down the straightaway and let off at the end it dies....I have played with it leaning it richin it.....and even had some nirto state series guys play with it and it still does it......I have sealed it...and put 3 glow plugs in it and it still does it....there is no bubbles in the gas line...I did notice a spot on the carb where the flywheel is rubbing alittle ...could this be stopping it..and if so can I shim it somehow.....I am running a FTrc8 clutch.

well any help will help...lol
