Took a break on this for a little while to fix the ignition on a Tecumseh powered Blue Star welder.
So I was able to cut the carb spring shape from the spring steel material. Edges were sightly rough but a little filing took care of that. I reassembled the carb with the new spring and reproduction carb diaphragm and check valve. It fired right up after priming the lines with fuel using a little air pressure! Only adjustments I've made is the mixture screw to get the rpms right for the correct voltage.
Calling this one done for now I guess. Might need to keep an eye out for another OR tool to rebuild!
