thanks rocky! had the mp (p-40007039) on it on the break-in stand and it quit on me (cross shaft for the pump lever worked out) with maybe 2 hrs run time on it. i put it back together and broke the ear off the pump reinstalling it (dumb a**). i bought that pump in 2002 for $38.00 and now they want $150 to $190 for it (must not be a market for mech. pumps or the new 1s are made out of gold). thanks for the info. dave
