P. Nut, I may have to get one of those Ryobi carb spacers. I ground down mine about 1/2 inch and am a bit worried if I got the bleed channel carved in it OK. Attached are some pictures. The first shows the 360 degree oil sump. Very simple idea, with splash lube. The other photos show it running with the prop spacer, ground flywheel, shortened carb spacer, and exhaust pipe. The original muffler was 8 oz, this pipe is 4 oz now and I will eventually trim off a bit more.
