colemanct200u torque converter problem

[houg]

hi everyone i owned many minibikes as a kid, i just bought my son a colemanct200u for xmas i also ordered a tav2 torque converter from ebay well i went to install it only to find that the coleman has a 5/8 crankshaft and the torque converter drive pulley is 3/4 so i searched the web only to find that i cant get a torque converter with a 5/8 drive pulley there all 3/4 any one have any suggestions on how to make this 3/4 drive pulley fit my 5/8 shaft or are there any jackshaft mods i can do to make this slow thing a little faster??

(link simply used to give you an ideal what I'm talking about. Was at the top of a quick google search and used because I'm lazy. There are cheaper ones out there)

i all ready have one of those unfortunately it wont work because the key that is in the pulley is not deep enough to engage the crankshaft keyway it will go into the sleave all right but not deep to go into the crank and will probably slip and ruin the crank
