Brad,
Good that your clutch came off the engine you want to run it on. You know it fits.
Now. you do need to confirm the type of chain the sprocket fits.
#35 is what we run in vintage.
If it is #35, then the wear on the teeth won't keep you from getting some good use out of that drum.
If you keep the chain lubed, it'll run for quite a few hours before the drum is finished.
BTW, I have developed the practice of lubricating the chain by squirting a little PJ1 on the clutch drum sprocket, then spinning the axle to distribute the lube onto the chain and onto the axles sprocket. I do this about three times, until the chain looks wet. I used to spray the entire chain, and then spent lots of time removing the PJ1 that was slung off the chain when on the track. I figured that something like 80% or more of the lube I sprayed on the chain was slung off in operation. Anything more than a thin film of lube serves no purpose in any event. I get minimal drum sprocket wear and about 90% less mess lubricating the chain this way. I do the same thing on my KT100 Emmick Avenger modern race kart as well.
You will note that you can run a needle bearing drum from 10 tooth on up on Rev Grips. That's why I run nothing but 10 tooth drums on my 820's.
There is no doubt that Jim Donovan's Max Torque clutches will give you much better performance, but I am saving mine for when I mount up my Bonbright Vintage 820's.
I am hoping that Miller will share with us his tricks for messing with the Rev Grip clutches. He's quite an innovative individual.
