Carb mixture/pilot needle snapped

Postby 1200Doug » Sat Aug 01, 2015 10:59 pm



My Carburetors pilot screw broke off in the carb body. Is there a way to use compressed air or something to get it out?

Compressed air? No, it's screwed in.
How'd it break off?

Whoever worked on it last over tightened it and broke the brass tip off in the aperture. Screw came out sans tip.

Tried compressed air but the other end is 4tiny holes in carb throat. So I shot some sea foam deep creep in and then cut a vacuum hose on a shallow angle and tried to shoot it out even blocking another small aperture that was connected near the slide diaphragm to no avail.

Last resort was smacking it on a block of wood. No deal.

It has to unscrew before it will come out.
If it's down in the body you'll have to use an easy out.

this is a quote from Randakk (a VERY well known rebuilder of Goldwings:
Removing Stubborn Idle Mixture Screws:
Another problem you may come into when working with GL1100 carburetors is dealing with idle mixture screws that seem to be super glued into the carburetor bodies. They don’t always come out as easily as the GL1000 carb idle mixture screws do. If one of those screws has a broken tip that has wedged into the carb body, then that carb body can be considered trash.
Rarely have I been able to save a GL1100 carburetor with a broken idle mixture screw tip stuck in the idle orifice. There have been several occasions where I had to use a thin cutoff wheel and die grinder to cut a screwdriver slot into a broken idle mixture screw. Then a flat blade screwdriver usually gets the screw out.”

Good luck, sorry for your loss.

I cant imagine its tougher on a GL1100 than a 1200. Either way this thing is stuffed.

Sad part is every other bolt the previous mechanic touched is loose. Figures he decides to make up for it on the little brass idle mixture screw.

The replacement i ordered still has the factory cap over it. Not only will i have a body, but a jet thats been untouched. Ill be able then to see how many turns out honda sets it from the factory.
