I do not have S/N at this time.

Thats ok

 

the intake is 0.015 and the exhaust is 0.025

turn to top dead center on number 1. adjust intake on 1,2,4 and exhaust on 1,3,5

turn 360 then adjust intake on 3,5,6 and exhasut on 2,4,6

Each cylinder has 2 intake valve and 1 exhaust. The exhaust is on the left from the front of the engine and number 1 is also in the front

DO you know how to get the engine to TDC on the number 1 cylinder?

Yes, I do. I have the front cover off to fix a leak, so I can see the timing marks at this time, thanks!!!

You can also pin time from the flywheel end too. If you ever need to do it again. Just need to make sure intake and exhaust are loose when doing it that way...otherwise you need to unpin and turn it 360 degrees because you are on the exhaust stroke.
