    340cc arctic cat Fuel/oil ratio

    Hey y’all. Down here in texas I’m very lucky to have gotten my hands on a snow mobile motor. First one, very cool! Just got my hustler fully restored and ready to rip for another 30+ years. Just need the fuel ratio and I’m on the trails. If you happen to know on hand, leave a comment. Thanks!

    How old is this engine? Anything from the late 70's, early 80's were oil injected. If you are going to premix, 40 to 1 was the standard mix a lot of guys ran although many guys run 50 to 1 using a high grade premix oil. I believe that it is different from injection oil but it has been a few years. I would start with the 40 to 1 and see how it runs. if you google the question you may get different answers. Being in Texas if you are in the warmer end then 40 to 1 would be my choice.

    I’m not sure the year, I’ll go look at the # on it. It’s not oil injection unfortunately. Thank you!
