RE: briggs 4 stroke prop?
maidened it today with an 18x8 prop (only one I have on hand drilled to 3/8"), a bit too much prop as it seemed to turn around 5000rpm and COG too high (flipped it), thinking of trying a 14x10 or something if I can find one (got to check my stock too). Lowering the engine is pretty easy the way it's mounted. The engine ran pretty good until I flipped it, I think I might have the fuel lines backward or am pulling air at the splices in the lines (didn't zip tie or anything, easy enough fix).
I'll have to get a pic of my new pull starter... some people might find it a good way to start magneto engines... I have about an hour into it and just stuff sitting around, kinda nifty.
