Yahama C25ELRV 2 cycle 1997 Long shaft

by Alfred
(Marcell MN USA)

no Fuel unless I use hand pump.
Installed new Fuel Pump. No pressure or vacuum at Block port to pump. Engine over heated when Water pump failed. Replaced Water pump works great.

Could the seal on the Crank shaft be leaking between the 2 Cylinders

Engine Idles smooth till Carb runs out. Then I hand pump more filling Carb & fires right up idles smooth till runs out again.

Cyl compression 75 psi
