I'll try and source another grade of felt Erny, I've broken quite a few on the choke arms BUT the last ones were much better. Bryan found them easy to break BUT TBH I found them ok but then I've had far more practice with how the break, what causes them to break so I can understand why Bryan found them hard to fit. Watch this space. No harm in asking the firm I suppose but it could be a problem if say they make a few hundred for you and then you find they also break easily and then you're stuck with a set of really small, really expensive doilies.
Ok, so just 1,6mm wide "wall' really small - let's see what they sayDo you know also "thickness"?
IIRC the sequence for the throttle shafts, starting from the throttle arm itself is Cupped washer, spring, flat washer, flanged washer, felt washer and on the inside of the carb boy there is a nylon washer. Just off memory. The cupped washer retains the spring, the flat washer is for the spring to sit against, flanged washer presses against the felt washer which fits inside a recess in the carb body, So I tend to fit the felt washer first after soaking it in light oil so it lubes the shaft running through it and also aids in dust retention and sealing, the flanged washer is the same size as the felt washer so no it doesn't sit on it, the flanged washer is to centralise the shaft of the throttle lifter and also to keep the felt washer pressed into place. The flange faces inside toward the carb body.
That's the choke Matt.
This shows pretty much everything on the 400 carbs.https://www.vintagebikebuilder.com/cb350-400f-carb-rebuild-demonstration.html
