Hi everybody

I just broke the idle needle in my model b carburetor and wonder how to change. I am a beginner...

Can i just pull it? Is it a good idea to drill a screw for better halt? Can anybody get me some instructios, please?

greetings from overseas

What is broken here is not part of the idle system. It is the power port tube and is a press fit into the casting. You may be able to simply pull it out with a needle-nose pliers. If not, the remaining piece may be removed using a 0.125 inch or 3mm drill bit after being careful to have the bit centered in the tube before drilling it out.

The Model B carburetor will still be functional without the tube but it will be lacking the power jet feature which is a primitive version of the accelerator pump feature found on newer carburetors.
 
Another option is to thread the part and insert a screw to pull it out. Try a 4-40 screw but if that does not work some other size.
 
Who is the guy in Denver with the big shop? Doesn't her specialize in these? I think he even makes the power jet tubes, and I'm not talking about using one from an ink pen other. I hate to say it, but if you start messing with it you may damage it beyond repair. Best to let someone that knows what they are doing.
