thanks for that link ken. im gonna install one on my wing. since oem pump sits lower than carbs, they are all going to be junk used. i will have to find one with a spring return diaphram to run off a intake runner, unless yall know an area on the engine to get a push/pull like crankcase pressure/vac. i may tap a hole in a valve cover to see what kind of pos/neg pulses are there.
thougts? i would really like to run on of the kawsaki pumps like on mowers. they are as reliable as it gets and dont care abouit water or dirty fuel orextreme heat........they just keep pumping!
