If you are talking about the "cap" on the FUEL screw (located on the front lower part of carb in front of float bowl), DON'T DRILL IT. Take a file or dremel and file the tab off of the cap just enough to clear the flange on the float bowl. You can turn the fuel screw in (I think) to get a better angle on that tab to grind it off.

Once done, you still have some of the tab left as a pointer/indicator to help count your turns in and out.

I did what james did, but its alot easier to do if u remove the carb. Lot more work though. Regards
