i got a briggs 800 series ohv 8hp engine for a minibike, i want to get a little more power out of it, i have a briggs animal carb laying around, would that work for the engine i have? also does anyone make a cam, con rod, crankshaft and flywheel for this motor? and where could i get some heavier valve springs, and what weight should i get? i want this to be fairly low budget. i just want to be able to rev this a little higher without breaking a con rod or having the valves float. any recommendations for what i should do to just get a little more performance would be great. im not going for a open mod drager just a little more power out of this 800 series. also should i get an offset timing key? and how many degrees? :shrug: thanks for all help.
