I bought a pile of saws a while back and have been bringing them back to life. My current project is a Husky 240S. It has a Walbro HDC carb on it and I ordered a kit to rebuild it. The “nub” on the diaphragm that activates the lever that opens the needle is longer than the one that I removed. Given the age of the saw and the tool marks on the carb I’m not confident that the one that was in it was correct. I have set the lever to the correct height for an HDC according to my Walbro gauge. Before I machine the “nub” down to match the one that I removed does anyone happen to know which would be correct for a 240S? I’m guessing I will need to shave the new one down to match the old one but if anyone knows I’d like to hear from you. The one on the left is the new one.
