Re: 1972 Evinrude 50 HP 2 stroke fuel delivery issue.
Reeds are controlled by crankcase pressures ( motion of the piston).---- If there is a hole in the crankcase or the bottom seal is completely shot then there is no change in crankcase pressure.----Take the time and visit U-tube , there are a number of tutorials that explain how this all works.--Some better than others.----When you understand this concept of crankcase compression , the trouble shooting will be so much easier !
