Bottom spark plug is light brownish yet the top plug is black. Why?!? Just one carb feeding both cylinders so why would the top one indicate Its running rich?
If all is else is good what about a reed valves? there are two sets in my engine. If one set feeds the lower cylinder and the other feeds the top cylinder is it posable the new byosen reed i install after the rebuild are crap.
I think the factory reed valves are very good.-----Rarely cause any issues.------No idea why some folks want to install anything else on a 35 HP motor !!
Any suggestions on how to test the fuel pump for leaks? I just pumped the primer bulb on the fuel line from tank to pump until it was very firm and I didnt see any external leaks on or around the pump.
