The engine is a polaris (fuji) 340, from a 1979 cobra 340.

pretty sure its mag but easy way to tell is ring locating pins should always be on the intake side make sure they are and then which way the arrow points is irrelavant.

I have another problem
I have a lot of pieces for these engines and I don't know what is the color of the spring in the engine cluth. If someone have a document or info about that, I would be interested.

Is the arrow direction being discussed here Polaris specific?

Did my old Yamaha last year, pretty sure the arrows ended up toward the exhaust. Not sure though. Will have to look at the the ones I pulled to see what I did.

May have to take a peak before firing it up now that this thread has me wondering.
