Yes this I did check when I had the engine apart and it was in perfect condition, I then went ahead and using Lucky 7 engine sealer I applied a thin bead on the neck of the carb so when I fully seated the carb it was just starting to come out. I also removed the neddle valves and applied sealer on the threads, and then ofcourse I also applied sealer to the back plate. Once this was done I started the engine and brought it up to temp on the box (approx 200 deg) I then started working on getting a smooth idle with out dieing. Everything seamed perfect as if the problem was solved and then out of no where the engine just had a major jump in RPM at idle after giving a few revvs? and would not drop, at this point I sprayed the front bearing with brake cleaner and the engine died. This is what lead me to believe the front bearing is my issue but there is no outward leaking from this bearing as the block is completely dry. This was only my 3rd offroad race so far since coming over from Onroad and so far it has been a rough road LOL, I have ran about 3 gallons threw the engine between racing and running as many laps as I can during practice. This running issue has been with me for the past 2 races as I first was thinking the tank was my issue.

Thanks again for helping
