mini bike clutch size?

[gokart12]

im ordering a new clutch for my mini bike I have a tecumesh 5hp motor and the rear sprocket is set up for a size 35 chain but the front is I think for a 45 chain, any one know which size bore and keyway I need to order? I seen they have 3/4 and 5/8

thanks

Measure your crank with an open end wrench and see which one you have 5/8" or 3/4"

thanks I didn't even think of that lol, I just measured it and the 5/8 doest slide over and the 3/4 slides right over the crank shaft so im guessing its the 3/4 clutch that I need right
