Anyone have a source on a gas cap that fits this thing? Know this is an old saw. Picked up a load of wood earlier this summer and cut the heck out of it with this saw to save others. Just fixed the recoil start and had it cleaned for another long day. Had to cut down a line tree the other day, my brother in laws's saw wouldn't start so I pulled this out be use I knew it would and the gas cap broke when I went to fill it. I'm trying to seal it with Seal All at the moment, but I have loads more cutting to do. Desperately need a source of something that will fit, or an original gas cap.
