I was inspecting the cvt belt etc.. and after i took the belt off l noticed that the cvt Driven clutch cover moves up and down some if i grab the shaft and shake it. Is that normal?

Also i was wondering what brand carb everyone buys to replace the existing one when its trash?
Also i am deleting the 2stroke oil reservoir and running mix 40:1 in the gas tank. Can i just leave the hose the runs to the oil pump alone zip tied or should i remove it and use a rubber vacuum cap to block it off?
And my last question, what topend rebuild kits are good for these things?
