Yeah, the info here is right on, problem is finding decent drill bits. I went to a wholesale tool place instead of harbour freight. Bits were junk anyway, broke/chipped off the one I needed on the main but I got it drilled. The idle was worse, didn't even get started before it broke off, may be got a 1/4 turn before it popped. Went larger on the idle..too much. Now I got to buy an idle jet and start over...or not. I am not messing with it unless I can find a better bit set somewhere. I used a pin vice and I know how to use it. Pissed off and jetless Tom
