I picked up a 2375 WT yesterday also Mark. It runs great and I don't know if I'll be doing any porting to it because I have no idea how to. I'll just have the slowest one at the GTG's LOL.
You don't own anything really slow, but you better not port it or you will be throwing rocks at the 260
As sure as I've ever been about anything Bob.
Your are correct, on the flywheel side carb bolt being the stinker. There not much of a challange for me anymore though.
