I have been having good luck mixing at 32:1. Then I fiddle with the jets every time I go out to make sure that my sled will be running good.

A lot of the older ones call for 25:1, but like I said, been having good luck.

I've always used 50:1 no matter what year. I was told by a small engine mechanic that you can do this because of the new oils.

50:1

Up till the 73 model year, Doo called for a 20:1 for sleds, in 73 they went to 40:1, after 74 they all went to 50:1 except for the racers.
