Stihl Ms441 mixture screws

[mmartone]

I just put a 441 back together and ran it some, doesnt seem like the mixture screws move very far. I would like it to be a little more rich on the top end but the screw only turns 3/4 turn stop to stop. Any way to break/fix this so I make this thing 4 stroke?

I haven't had a 441 apart, but the reason you can only turn the screws so far is due to limit caps on the adjustment screws. I imagine it is similar to my 361s carb, and I outlined how to remove the limit caps in my muffler mod thread. Check it out, should help you get them off that 441. ;D
