Gonna take a little digging to find info guys. Here is where I posted in 2014 about having a different carb. No I know that doesn't prove Cadet used different ones. I may be wrong about that. Next time I will look at the parts book, we have the original IH paper parts book--sometimes I don't trust the modern updates.
Anyway, here is where I said I have a different carb. Don't hold me to it but I think it was a LUA6 Walbro, or something like that. Go to post #8

In the meantime I'll keep digging and see what I can come up with regarding carb options.
