Fits 192/192t from my reaseach. Was in a box. Took apart and pump/diaphragm looks good. The other flat diaphragm had a lil shape to it telling me its used. It was dry as a bone inside. Did the treemonkey test to it and it held 20psi of pop-off pressure on the mityvac. Has limiter on high side. Does it need a kit, i dont know cuz i dont have a saw to test it on, but i wouldnt think so based on other carbs i have opened on running saws. I just did what i knew how to do to perform some sort of test on it. Lets say $25 FnF or add 3%. Shipped to lower48.
