    Polaris snowmobile need help

    well more like the engine. i baught an engine off ebay for $10 and nothing is wrong with it i just need carbs which i have on there way (banshee carbs). pipes again on there way and banshee pipes i will mod to fit. now i just need a cdi and coil. will a banshee coil fit? this motor is air cooled by the way maybe and early 70's so i need to id it i will get pis tonight but i believe it to be an early apollo. motor is going on a gokart project but i need the brain box before it gets running. if anyone has any experience at all with the older air cooled polaris 340cc motors let me know.

    Try to find some numbers on the case and cylinders, should start out like EC-----. Could be from a colt, or if you're lucky a TX. Good score for 10 bucks.
