Re: I hate 4 Strokes

In most cases there is no real load on the key after the flywheel is installed. So in a case like this I’d suspect that the surfaces weren’t clean and dry, or the flywheel nut was inadequately tightened. It’s not a bad idea to use some valve grinding compound and lap the crank taper to the flywheel. That will at least tell you if there is full contact….

I’ve read quite a few complaints about the carbs on small 4-stroke outboards and difficulties with clogging. This doesn’t make sense to me: The technology of carburation for 4-stroke engines in this size range is hardly new, and engines on lawn mowers, snow blowers, generators, and suchlike don’t have super-tiny orifices in the carb. This sounds like a design defect to me. What make are the carbs?
