Put together a blown up 350 Husky with a 346 piston. Everything else is stock but it sure seems Snappy!
I did not have the correct long screws for the muffler so found some stainless steel that were even longer. No problem for the 350 because the holes are not blind and lots of meat for the bolts and even past. That muffler would have to come out a long way before it fell out. Of course it may melt the case by then but the loud noise should alert any reasonable person to something wrong. Yea I know some operators are not to reasonable.
