Re: mixture?????

If it is a one cylinder aircooled, mixture is 32:1.A model number would pin it down.Motors were built by a number a builders.

Re: mixture?????

thanks for the reply. This motor was a hand down to me to bad the plate with the model # is no longer there. It is green, white, and black so just from what i've read I think its in the 80's. Air cooled I believe and yes it's one cylnder. So in one gal. of gas how many oz. of oil? 32? thank for the help

Re: mixture?????

32:1 would be 4oz per gallon. Be sure to use chainsaw or weedwhacker oil.

Re: mixture?????

I had the same colored Gamefisher and it was a 1982. If I remember correctly the mixture ratio that was printed on a sticker affixed to the cowl read 50:1.
The motor was a Tecumseh that was basically a lawn mower engine.
I could be wrong so if nobody else chimes in run it at 32:1.
