Naaa, you don't need a new tranny. Grub screws are common. If you can't decipher the manual for right size screw, then bring it to a LHS, they usually will have a bunch and one will fit. Its a small one, probably 3x3, but I am not sure of the right size. I don't have the manual, maybe someone else does, and can check, but I think there is a spring under the grub screw, which controls the shift point, so you might need that too. Hopefully, someone with a manual can check.

Doc, I think that grub screw is history! I can look into the hole and just see the threads... Do they even sell just that screw, or do I have to buy a *gulp* new transmission??? I was wondering about that hole the first time I looked at it, and wondered if a screw went missing...
As for the HPI easy start, $50???? That's crazy! To remove a 'more' complicated pull start, to just install a plate with hex in it??? WOWSERS! I guess I will just fix the recoil instead...
