I'm a little embarrased to say how I really stripped the threads, but anyways.....The mag engine came with 4 cap screws- 2 long, 2 short. The two long ones were in the carb bag, so I assumed they were the ones to attach the carb. I put one screw in no problem. When I tried to put the other in it was too long and was hitting the other screw. I was trying to figure out why Magnum would include two long screws for the carb knowing that one was too long. Out came the dremel and I shortened one. I took off the little burrs on the end of the screw then started screwing into the hole. Well I guess I didn't have "clean" threads where I made the cut, so I essentially stripped the hole. The weird thing is that there was barely any resistance when using the allen wrench, so I figured all was well, until the screw kept turning and not getting any tighter. [:@] Anyways, I opened the bag that had the muffler and low and behold, there were two shorter cap screws, presumably for the carb. Oh well, live and learn.
But do you think getting a slightly bigger cap screw will actually re-thread the threads on the inside of the carb? The metal or whatever material the carb is made of is so soft I'd think it'll just keep stripping.
The lock washer was on and I admit I didn't strong-arm the screw.
