As long as there is good smoke throughout all ranges I dont worry about it. The front bearing is defiantly a weak spot. I had one go bad under a gal and the other GRP I run has over a gal on it but I know soon it will go bad. Install TKO's and forget about the front bearing. Did you seal the carb and back plate? and how easy do the low, high and idle screws turn. If they turn easy then the carb needs an o-ring kit. The o-rings in this engine dont last too long, I have seen fuel come out of the HSN because the o-rings were bad. I always carry spare o-rings.
its not the clutch. ive replaced the clutch twice since having it.....
i checked for air leaks and found nothing, there isnt fuel on the bottom of the block after runnin so i dont think the bearing bad. and the needles are tight. im just going to lean it out and have it run around 240(guessin this will be where it at) there was tons of smoke at 268 last saturday but thats to hot..... if it blows it blows. im tired of dealin with this engine. my pinch is prob close to being gone soon(maybe 2 more gallons) and it has like 3 on it so o well no more grp for me
