Re: clutch problem
Might be a worn first gear. First and reverse are the same if I remember right. It's VERY easy to drop the transmission on these and it's not overly heavy. You might hit up one of the parts guys in the marketplace for a new first gear then start pulling the tranny. I've got a full writeup, bolt by bolt, in my build thread here.
Even if you don't need that gear, it's good to have extras on hand for later. If you do need it, it should be there by the time you're ready for it.

Re: clutch problem
Your clutch is not releasing fully. Check fluid, then have someone watch the linkage from below as you cycle the clutch (NOT running).
There is an adjustment for proper clearance (not too much, not too little) that may solve your problem. I doubt that the problem is in the tranny. I also wonder what technique Fetch uses to make tranny r&r easy. I have done mine twice over fifty years and would say it is hard to get to and VERY heavy. |

Re: clutch problem
If you can believe the info on the internet, the three speed SM318 weighs about 65 pounds, and the four speed SM420 weighs about 135 pounds.

Re: clutch problem
Well there's your trouble! Your transmission is 70 lbs too heavy!
