Screw broken in carb body

Recommended Posts

Hi,

When attempting to adjust the fuel screw, it snapped off at the threads in the carb body. What is going to be the safest way to remove this without damaging the carb body?

Thanks

Mike

Take the carb off the bike. Remove the float bowl, see if enough of the fuel screw sticks out to grab.

A fuel screw should always turn super easy and never be tightened more than barely finger tight. You may have other issues once the screw is removed.

William,

It was the first time I touched the screw in 3 years. I decided it was time to replace it with a longer one. The screw would not move in either direction and then it snapped off at the threads. There is none sticking out to get a hold of with plyers...I guess I am looking at drilliing it, just worried about hurting the carb body itself. I will keep you posted.

Snap-on sells a really good screw extractor set for around $80. That price was many years ago. It has drill bits and centering guides included. The extracters are not tapered and allow you to turn the screws both ways.

That being said, I agree with William1. If you have another screw to take in to show the machinist what is in there, bring it along. It would be terrible if he drilled into the metering part.
