I am rebuilding one now for someone 4 hrs away.-----Broken rings on 3 pistons.-----He said it would still run , but a little hard to start.-----I feel sorry sometimes for folks who just do not know how these motors work..----Or know how easy these motors are to diagnose.

It is NOT operated by vacuum.----The pump operates by crankcase compression PRESSURE !
