Chris, looks good. I don't think that they'll break down, unless they were to "sit" in gasoline for a peroid of time? I'm betting they'll hold up for a long, long time. Even if they break down in 5 yrs, you can simply replace them anyway without having to dismantle the carb anyway?
Any chance you tried making 1/2 a retainer using the other idea?
I haven't had the chance to try it myself. Got caught up with something else last night, and I just got back from Columbus as I "Might" be buying: another tractor, C-22 mower, 42" Woods mower, 2 54 grader blades, a plow, set of rear wheel weights, and possibly a Farmall A (didn't tell the wife about that one yet
), as well as I may have found a potatoe plow/digger for a Cub? Gotta go thru some manuals to make sure the items I found are what I "Think" they are.
Good thing BD is at Cubarama or else he'd be sniffing around in the territory too?
