Default Centrifugal Clutch

What should I do to keep my clutch from sliding side to side on my Predator 212's crankshaft? I need it as far out as I can but I need it to stay in place.

Lets see some pics as to whats the issue???
How far over is it?..... It should be at the shoulder of the shaft...... If anything, you might need to move the motor or sprocket over....

If no set screws then: place washers/spacers between block and clutch as needed, then on the other side of the clutch place washers or spacers as needed, then put a bolt in the crankshaft, being a 212 there should be threads

Simple as that, but if you have set screws it’s less a hastle

I have some 3/4 id tubing that I use to make spacers. Then I put a bolt in the crank to hold it there. Also, I’m just a little paranoid about having something spinning at 3000+ rpm held on by just a set screw.

With the chain on and at a proper tension.... its not going anywhere... set screw or no...

Bolt on the shaft is a good recommended step to maintain lateral clutch movement to a minimal..

Agreed, I use spacers just to keep a little less stress off the chain!

That and sprocket wear.. Once it starts to thin out... the teeth will go to crap soon after...
