Missing Washer

[RonW]

These washers (red arrows) are so thin and flyweight that a slight breeze will blow them on the floor 50 feet away. They cost $7.50 oem. Has anybody replaced them with something else? D-ray refers to the part as a 'bushing' in his carb video. Screenshots, below.

My Valk is missing 1 on each side but it doesn't seem to affect the choke operation at all. Maybe someday I'll do something about it.. so long as the slider still moves freely it seems a non-issue.

I've not had the carbs apart enough to even know about those, and it's kind of hard to see what you're showing. I thought they looked like rubber cushions.

Could they not be replaced by something else, like nylon washers? Thin and slippery.

A nylon washer is thin enough, and I've actually seen it at the hardware store. The washer fits over a shoulder (red arrow), so if the washer's too thick it'll bind the movement of the choke linkage. The oem washer is thin rubber and flexible like a rubber diaphragm. There's two washers. The larger washer seats below the choke linkage, and the second washer seats on top of the choke linkage. D-ray refers to the washers as bushings and the term's more appropriate for its purpose of preventing wear & tear, although the washers also serve as spacers too.

Boilerplate points, if you remove the washer and conveniently place it on top of the engine, it'll pull a disappearing act on you. Also, nylon melts at 428° so it won't deform in the long run, I think. Otherwise, you could use a piece of plastic from a plastic bottle etc as a replacement. The screenshots are the order of installation.
