Centrifugal clutch

[deadbucker]

so i need a centrifugal clutch for my go kart and when i look for one to buy online they come alot with #35 chain which i have but then it says 11, 12, 13, 14 teeth... idk what is better?? or what so is 11 better or is 14 better? whats the difference? also the diameter which is good bigger or smaller?

For MOST fun/yard/hobby kart purposes, you'd got with the LEAST amount of teeth available, to help achieve a suitable gear ratio.

Depends on many factors.
What do want your drive ratio to be?
5 or 6:1 with 10 or 11 inch diameter tires is considered average/normal.
12 tooth clutch with 60 tooth driven sprocket (60 divided by 12) would be 5:1 ratio.

ok

ok thanks for that answer cause thats what im using the kart for but i want to understand it not just do it cause someone tells me to. i am making the kart and if i just tell the person the least number of teeth idk what im doing so i kinda wanna understand it i looked at a couple websites like wiki and stuff but didn't really give me the whole picture. thats a important part if your using like a snowblower or a chainsaw engine cause they dont have clutches on them and would just take right off when u started it! so i kinda wanna know more and also what about a keyway? some come with one and some come with a built in key... idk what that means. thanks for the simple answer but cence im making my first kart i would like to know more.
