49cc 4 stroke stalls and blows smoke out of intake

My 49cc engine runs good its the whole clutch assembly that sucks.

I need one of these but that means a whole different crankshaft or engine. Maybe one of the 53cc ones they come with tapered shaft. Probably still aluminum rod. I opened my sidecover and its a steel rod on a straight shaft. (ebay motor). The engine runs fine even without the floating governor gear that I removed. The bushing would have seized if I didn't smear it with grease again today. Its not even an oillite its just brass.

Grubee Sells Belt Drives for both drive systems you just have to email him, i've gotten it before.

Is it a ball bearing clutch or a bushing the shaft actually spins on the bearing and the belt gear protrudes on the other side.

I don't know if they are selling the 2d couldn't find it. I might have to aquire a kawasaki fj100 and put this on it. There is an engine called the Titan 100cc and I think its a kawasaki clone, its an option for slightly more hp than a harbor freight. https://www.grubee.net/collections/...tor-5g-belt-drive-transmission-18t-70t-9t-56t

The 98cc predator clone clone is poop, there is a reason the 79cc took it's place.
