Viewing a rib tomorrow with a 40hp yamaha 2 stroke but completly forgot about testing the engine for compression
I can't sea trial so it's vital I get one
Does anyone know where I can buy one tomorrow morning? or does anyone have one that I could borrow for a few hours?
also is this right;
Disconnect fuel line
remove spark plug and screw in compression tester
turn engine over and read compression
repeat for all cylinders
what should compression should I be looking for in a 40hp Yamaha?
