Hello, I have a 1978 kromag. When I was in college in 1980 I was doing a project and got a puch motor, with markings ZA50 on it. This motor has never been used. I replaced the kromag engine with this one, everything mounted exactly the same, only the clutch cable attachment to the engine was a little different, but I took care of that.
My questions are:
Choice of gas - I would guess, 89 unleaded 50:1 2-cycle oil
Is this puch motor a one or two speed motor
What oil should i use in the gearcase
What is the correct spark plug
Is my old motor of any value to anyone
