Well, I screwed up I broke a valve tappet on my 2 hp briggs. I'm not sure If I want to replace it but in the mean time I have this Its a 5 Hp Briggs & Straton gas engine, it came off an old generator that quit working. The problem was with the engine, the intake valve was stuck, I fixed that though. The the cam is already timed for 1 intake and 1 exhaust. A little fine tuning will help though, but now I have to add 2 additional lobes exactly opposite of the other 2 lobes. I would like someone to machine them, but will probably end up welding them. Ok, the 2 lobes needed: Would anyone like to machine them for me? I will pay you of course, but I just need 2 little lobes machined so I can weld them to the cam. Hope everyone takes an interest in this, its an easy way to build a steam engine. Cedge, did you recieve my PM?
