    Briggs 3 hp Engine knock (or something)

    Finally got to finishing the engine for the ARCO. I needed to swap the crankcase cover for one that would accommodate the clutch guard bracket, so I pulled it and put on a new gasket and torqued it in place. I lubed the journal before reassembly. I swapped carb and tank for a smaller tank...

    Cheap Knock off TAVs on Ebay

    Is any one using the Cheap Knock off TAVs on Ebay? If so what are the likes or dislikes? Anyone use one on a Big Block or a 1 inch shaft engine? I assume that Comet is out of business and no Patent Rights to worry about so that's why there are lots of the $100 TAV's online.
