The engine that comes standard with every Enticer 340 is a two-stroke, fan-cooled twin engine designed for this snowmobile. It reaches a maximum horsepower of 32 at 6,500 rpm, and a maximum torque of 25 foot-pounds at 6,000 rpm. With an engine size of 440-cubic centimeters, the Enticer can reach a maximum speed of 55 mph on the snow.
The compression ratio for the 1979 Yamaha 340 Enticer snowmobile is 6.9:1. This ratio indicates the relationship between the cylinder's total volume when the piston is at the bottom of its stroke compared to the volume when the piston is at the top. This compression helps optimize engine performance and fuel efficiency.
Answer this question…there isn't a specific mix but you don't want to much because it can cause the spark plugs to foul out. if you do put any in put a little bit .also always run your snowmobiles on premium fuel

their really is not a specific fuel octane mix. if you just run premium in it, it will be fine, but if you do put octane in, just put a little bit in it. because it could make your fuel too rich and foul out your spark plugs.

most likely a crank seal is leaking, or carb boots. have a shop test the crankcase for leaks
