air screw cap?

[redhotspike]

I'm working on cleaning/rebuilding my carbs. However, I've run into a roadblock: I can't get the cap over the air screw to come off...I've heard you can drill it out, but I'm a bit weary of taking a drill near my carbs.

Any suggestions for getting that ridiculous cap off?
Much appreciated.

Screw a screw into it and pull it out with vice grips.

thanks - going to try it out

tried the screw...that darn cap wouldn't come out...
I sprayed some liquid wrench and I'll try again in morning

You could use a spring-loaded center punch to keep the drill bit centered (or to keep a screw centered while you drive it in). You don't have to drill out the whole cap (in my limited experience). It comes out once you get a tiny drill bit through and wiggle it around by hand.

Use the drill. Don't be afraid.
Drill the hole, put in a screw and pull it out. It really is that simple.

That is the method, jet kits actually come with the bit and the screw for doing it. drill a small hole, screw a screw in just far enough to get a good bite and yank it out. Be careful to not drill far enough to damage the screw underneath.

Drill

I think a variable speed drill is a pretty safe way to do it. If you still can't get it, Bill (Chef) will come over to your house and get it out for you.

Use a brad or a tiny nail as a punch and tap it in dead center.

There is a slot running across the screw under the cap

Tapping the nail in usually deforms the cap enough to pull it away from the sides. If not, use the depression you made to try a screw.

If all else fails, you can use a hand drill on it

ok so i got brave and got the drill out...needless to say the drill is dead (not the battery)...lol anyone know anything about fixing drills? jk
so i think i'll attempt to chisel away the cap - about how thick is the cap?

[Steve]

The cap is about 2mm thick (less than 1/8 inch).

There is usually about twice that amount of room below it before you get to the mixture screw.
