Air screw F****R

[baz]

Hi does anyone have any ideas on how to get a seized and chewed air screw out.

I'm not being flippant.

What carbs?

Probably will not make much difference, but it might.

Use heat on the carb body (propane torch), along with pent. lube like PB Blaster. Turn the screw back and forth, both in and out, until it starts to move. Do NOT force anything and strip the head of the screw. If it's too late on the screw slot, I've extracted a couple of stripped screws from carbs before by cutting a new slot in the screw with a dremmel cut off tool. You will have to cut down the tower first though.

I thought of that, too, Ed, but he said "air screw" and the VM carbs that have an "air screw" don't have a tower to cut down.

That is why I asked for more details about "which carbs".

What's a good replacement for the 4 screws on the top of each carb? Mine came out ok but they are looking a little bunged up. I would like to replace them with new screws.. can I just go down to the HW store and match?

Thanks,

[Steve]

They are either 4x14 or 4x16mm.

There are some kits available that have stainless socket-head screws.

For VM carbs.

For CV carbs.
