Heya folks. I’m curious is there’s any recomended/baseline for plunger drops while looking at diaphragms. Paul linked a video for Chito’s post earlier showing the slide drop rate in order to determine if new diaphragms are needed. Is there a good “range” to be in for the drop? What’s a really well sealed set of carbs look like vs. a well worked runner that’s going strong?
Fooling with a 2nd set of all original 34’s from fleabay, internals (for the most part) in excellent condition. No cracks/tears in the diaphragms. Original enrichner plungers - rubber is pliable in tips, replaced the enrichner seals. Drop count = 13 seconds.
The originals have new JBM diaphragms, new plungers (I admit these are Mike’s) which were a really tight fit & new seals. Drop count = 24 seconds.
I’ve seen varying reports when scraping out BS34 articles here mention 10-15secs as a target while a few posts mentioning the 20s. What impact does this have on properly timed/valve adjusted engine under load overall?
Heh sorry for the long post, just trying to get a better understanding.
