I ordered a frank bowman ring yesterday, so im hoping that it doesnt take too long to get here. I also picked up some "threebond" similar to yamabond, so i can do away with the backplate gasket and the head gasket. My 16-6 prop arrived today, so I cant wait to get this thing on the test stand again. I decided not to run the engine again til the ring came. Also the weather here has been just awful. Where the hell is summer? I think im also going to get a carb kit. I noticed the last time I ran it, the idle was pretty poor, and it would pick up and slow down. Kind of a brummm...brummm...brummm. Just like I was slightly reving it. I guess i should have got a video, so you guys could hear it. I pulled the diaphram cover off, and it looks good. I suspect that there is some crap in the carb. I forgot to put a fuel filter in it. (was in a hurry and had changed the lines) So i guess this is how i pay for cutting corners.
