got the 277 degree 780cc engine fired up for the first time tonight.. found a small oil leak at the feed tube banjo ( my fault, not torqued) main issues are.. left side carb is dumping fuel from the air filer ( stuck float?? ) 79 bs38's full rebuild. also my engine did not shut off when turning the key off?? I verified no power at the pamco with the key off, unless something is back feeding?? or with the increased compression could it be dieseling? the exhaust tone did change with the key off, but the engine did not die... engine only ran for 30 seconds... any ideas??
