Pilot screw extraction

Kirk Creswick
I picked up a set of carbs and I'm in the process of rebuiling them. The needle of several of the pilot screws twisted off during removal, and are stuck in the carb body. Anyone have experience dealing with that?

Also, the needle jets won't budge. Carb cleaner passes through easily. Any reason to try to remove them?

The jet's do wear over time. If you have new ones in your kit, replace them. The important thing is to use a screw driver that fit's. Most people use too small of one. as for the stripped one's. I would recommend an easy out.

It is only the small needle at the end of the pilot screw that twisted off.

I think I have the picture now. If you can not replace the seats. Try soaking the carbs in a solution of muratic acid, and water mixed 50/50. This should eat any crud away that is binding things together. Just be sure to remove any steel parts first (parts that a magnet will stick to). And DO NOT BREATH IN THE FUMES!!!

I managed to get them out by holding a sewing needle in the hole with vise grips and tapping on the vise grips. Took awhile, but they came out.
