An additional thought. I just realized a point of confusion in your note.
The big needle on the piston is NOT the needle we are talking about in the
needle valve. On your spare stromberg, turn it over so the floats face up.
Look at the hinge and on one side there is a nut in the corner. There is a
button needle in its center. THATS the needle valve. As the float goes up
and down the lil flap on the float bracket opens and closes the needle valve
to refill the float bowl. Gas in the float is sucked up the cernter tube
and into the chamber where the piston is and is regulated by the main needle
you see attached to the piston.

Thanks to Tom, Randall, and Dave for the info on the Stromberg questions.
Having gotten a pretty good look inside, the varnish is quite evident so
I'll
be taking the carbs apart to clean. But I would like to be as minimally
invasive as possible. I was told, drop the fuel bowl and clean the needle
but, having dismantled a Stromberg from the parts car to see how it's put
together, I don't see how dropping the fuel bowl gets me at the needle
without messing with the adjusting nut. Is that correct? And, if I need to
take that out am I getting into the Unisys thing or whatever it is in terms
of having to balance them? It wouldn't be something I wouldn't like to learn
but, for now, I want to try a combination of the KISS theory (to the extent
possible, anyway) and the "if it ain't broke, don't fix it theory" -- if
possible. When I dismantled the other, I pulled the piston through the top
and that exposed the needle -- but it also broke the seal on the diaphragm.
What are the ramifications of going in that way? Is it possible to get to
the
needle without either going in from the top or playing with the adjusting
nut? Will generously spraying carb cleaner into -- what? -- everything in
sight? -- perhaps do the trick. Everything else seems to be moving so I
suspect that the needle is stuck.
Any advice -- precautionary included -- appreciated.
Jim
