<VV> The YH Pump - THE final answer

[Doug Mackintosh]

Wow! When I asked my original question (does it squirt?) I thought the answer would be "yes" or "no" (or, since I know who I'm dealing with, Yes AND No). Geez, the discussion got so involved I forgot what the question was!
 
Anyway, I think everyone finally converged on the same answer, "it won't squirt unless the engine is running (or at least cranking)".
 
Thanks, I really do appreciate the answer (and the explanation).

In my memory my Spyder YH accellerator pump does slightly stroke with 
the throttle linkage. So I set out to confirm this.

I took apart a spare YH I purchased back in the early 80s, seeing as the 
one on my Spyder has not run in several years and will need cleaning to 
get apart.....

This YH performs just like Bob says it does! The accellerator pump shaft 
does not move down with the throttle linkage. The spring (lower) is very 
tight and the diaphram is slightly stiff. So the only thing that pulls 
the shaft down is vacuum on the lower side of the diaphram. If you push 
the shaft down with a finger (and a hard push is needed) then the 
throttle shaft will raise it, along with the metering rod. >>
