Picked up this 066 flat top the other day Looks to be the wrong switch lever/shaft on it. It wouldn't hold the choke closed on the carb on its own, had to be held down to keep it closed. Looks like someone filed it down so it fit in the slot. What would be the correct one for this saw? Part number? Or does anyone have one kicking around? Also need a flat top air filter cover. The carb box PN is 1122 121 0102.
