I removed the butterfly from my Zenith Stromberg and used a propane torch
with a very fine flame to solder the poppett shut. There were no ill affects
after replacing the butterfly. However, I didn't notice any changes in the
idle...But it did remove the poppet as a possible cause of any problems. (BTW
-
that ZS carb has since been replaced by the single HIF44 replacement that Moss
sells.)
Good Luck!

Absolutely none, that was what I chose to do (mine were causing it to 'idle'
at 2500 rpm while warming-up after a below-zero night) rather than fiddle
about replacing the butterflies with solids and risk getting poor alignment.
You can solder them just by removing the carbs from the engine and leaving
everything else undisturbed, but you will need a 50-60W iron, a 25W
electronics iron isn't enough. But if you *do* replace them with solids you
might shave a few milli-seconds off your 0-60 time ;o)
