Thinking this maybe why it ran at full throttle only, jammed over/open ? Remember I was thrilled that it ran at all !!
The only markings I can find are LMH (cast into flange) then stamped in small font 4-4-3 ?
I have a couple Walbro's around that came off Cubs but they are not going to interchange with this...
Did a quick look on e-bay and everything looked like modern plastic
Again I find myself asking, and ideas ?
