Mini Bike Tune-up

[high.rev.trev]

Ditto Hemi, that's what had happened to the Std 4hp 172cc Tecumseh on my Australian Deckston when I bought it ex Auction & was delivered (had throwen its chain knocking a hole in the crankcase cover, but the sneaky seller omitted to tell me:retreated back to his truck once $ handed over faster than the French Capitulating WWII )...
I've Incl a screenshot pic of a vertor on EBay, he's been selling for ages & currently discounted, just double check your output shaft dia - 2 x sizes: 3/4" & 7/8" I think , I"all go measure these autoclutchs for you. They have multihole drilled mounting bracket to fit many horizontal shaft engs both L head, ohv & Honda clone incl ohc. Just be careful about output chain size # too: #35, #41 etc.
Cheers Trev.

I put a 6.5hp preditor on my mini bike. Likes to kick the chain. You guys have any recommendations for a torque converter?

Yep - just noticed Hemi the 6.5hp Predator Engine Convertors are $79 on EBay - sold heaps of them.
That's pretty cost effective for both a clutch & constant variable ratio gearbox in 1.
