I have a NIB K&B Stallion 35, and I certainly wouldn't take $35.00 for it.
I ran Stalliom 35's on my c/l planes in the late 60's, that's all I ever used.
They cost $9.95 brand new. They were easy to start, electric starters
weren't invented then, and they ran really good.
Here's a good look at the part you need. Bill Robison might have one
lying around.
FBD.
