--Also, it dies when i open it up(full throttle) almost everytime. I tried, and many others tried to tune it. We tried to lean the top and richen the top and got the same result no matter which way we went.
--Im lost...someone said it may be the front bearing but if it were that wouldn't it leak fuel also and cause a bunch of dirt to build up there? It was perfectly clean when i pulled the flywheel.
I already seal the carb neck, back plate, HSN where it attaches to carb body with red RTV.
Any help???

Thanks, James
