First I want to thank all who have been giving me such good advice. I have been making good progress on the rebuild of my Carter YF 2100S.

I thought I would share some photos of my progress.

I was able to get the accelerator pump/diaphram shaft unstuck with the help of homer52 and others. It was really seized. I cleaned it, soaked it, and saturated it with penetrating oil. The key was finally getting it set up properly so I could tap it the right way.

I was also able to finally get the rusted idle needle out of the carb throttle body. I know many of the needles are brass, but this one was steel. Maybe due to the Korean war? The head was snapped off, so I brazed a nut on the end, and also heated the carb throttle body with a torch. I was then able to turn it out. It was very corroded.

I was also able to repair the small rod that connects the throttle shaft to the accelerator pump lift by brazing the broken parts together. Maybe it will hold.

I cleaned many of the small parts with an old ultrasonic cleaner used for rapidiograph pen points. White vinegar seems to work well.

The last picture I have is of the lower carb body. There seems to be three jets that maybe should be removed. I don't have the rebuild kit yet, so I don't know if I should try to remove them.

Any advice here?

Thanks for all the help, and I hope you enjoy the pictures!
