You got my curiosity up, so I took down a Montgomery Ward version of these engines. It has a Wico magneto, an aluminum ring for the rope and a stamped aluminum rope plate. I found a spacer between the plate and flywheel, which measured about 0.170″ thick. Funny thing about it is that it has an ID of abut a half inch and fits loosely on the 7/16″ thread. This one is different than my other MW, that has a poppet valve. It has a carb like yours; and someone, not me, had hand-written “KB1A,” on the little front cover of the carb. It was tagged that I ran it in 1996 and it ran well; although I don’t remember doing it, at this point.
Bill, Thanks for looking! I’m glad I went with my instinct on this one and added the two brass washers.
Mine were from a metric kit…… not sure what size ID, but they were a good fit.
Prepare to be boarded!
