Starter (choke) plungers

Simjim, I installed a set of the later vm plungers in the early carbs, longer shaft used the spool nylons and later lifting arms, for lift and lowering, bought a bunch from niche or jets r us, for other bike, longer shaft was used mid 74 and up, which you probably know

 

Soo unique the ribless choke plungers are, they Don't interchange. Altercations of the lifters would be required, believe me i've tried it. The castings sit in a different position relative to choke rod and lifters even though the holder plate was the same part number.

   Thanks asphalt900.
   Our experience with ribless carbs is limited.  It appears in the pic that the 'cup' that holds the rubber donut seal is longer on the later plunger, determined by using a crude method of holding a scale to the monitor screen.  It also appears that the overall length of both plungers are the same, tip to tip.  Are both estimates correct?

Good Ridin'
