the choke on these carbs is a cold start often only needed for a very short time not a choke as such the o ring on the choke wears as does the bottom of the plunger

If you do all that has been suggested to the carbs and you still have a problem with one cylinder you might want to replace the condenser on the faulty side. I had a good spark on both sides and the the carbs seemed OK but the exhaust was cold on one side. Turned out to be the condenser but be warned I had two faulty NEW condensers from a well known Guzzi supplier before I got one that worked. I found this out by swapping the old, good condenser to the other side and that exhaust pipe heated up. The bike runs well now but does require choke for a few minutes before it is warmed up. I have plunger type chokes.

If you dunked it in liquid nitrogen it would probably be rigid enough.....

I think it might just be a tad too cold to produce a flame then.

But it's the match that produces the flame......

Doubt it, but it's not helping the original question.

Officially it's a "fuel enrichment device" aka "bypass starting device" and all things being correct is only really needed for cold start in very cold weather, having got all my jets sorted out (partially blocked) I next used "choke" as normally this is in summer, totally flooded it, took a while for the penny to drop why it wouldn't start (cos I'm not doing anything different). This was the VHB carb's.
