[QUOTE="rumblefish360, post: 1974035417, member: 1189" [Then again, there was that dynamic duo that figured they could port there heads while the engine was running by dumping sand into the intake and rev’ed it up.QUOTE] there IS an old Dutch or Swede Motorcycle Racing trick to seat rings, sometimes called "Huff and Puff" basically you take spoonfuls of Dutch Master, or other powdered cleaners and blow em in the carb while Turning the throttle. Works Killer! I've even heard of people whose Rings failed to seat use it to get them to seat. Now about that Sand to port Heads,cut new valve seats, and regrind cranks, setting new cam bearing clearances? Does it clean the oiling system too? (EVIL GRIN INCLUDED)
