I have an et 250 that i am going to race 1/2 mile snow ovals. I purchased a comet 102c and was wondering what a good starting point for a spring and weights would be for what i am going to be doing any tips would be greatly appreciated thank you
Comet suggests A-1 and Pink comet spring. The Comet Red is a better all round spring. Pink is to soft.
Myself i like the old F-2 weight in the 338 single carb engine. You might have to lighten them to acquire the rpm you are looking for. The F series weights have a decent profile to match the supper soft secondary spring in these older sleds.
I run a Orange Erlandson Performance Inc Polaris primary spring. Only issue with EPI spring is...you will have to machine the cover and the spider to except the smaller inside dia of the Polaris springs.
Good Luck.
