...I have, with both '60s here.   I resolved my 4-door issues by 
ridding myself of the original choke altogether.  The '60 Monza still 
has its original choke and it is inop because the heat tube AND the 
port in the exhaust manifold are both clogged and stopped up... and 
I've not gotten around to changing either of them out yet.

The '60 Monza never goes anywhere in winter anyway.

Or rather, failed to open, period, after having been unheated by the 
clogged heat plumbing.

The real problem was carbon clogging of the heat tube and port on the 
right side exhaust manifold, twice cleaned and twice reclogged on the 
4-door before I got kinda sick of it come winter each year.

And the very nature of the way it was heated suggested that it was 
primed for failure.

The 4-door's choke is one less example for anyone to see because it's 
gone from the car.    ;)    Now I never have any problems with cold 
starting or hot-rich issues, ever.    ;)

The one thing I will admit is that the '60 choke, like a Corvair 
transaxle, is gloriously complicated and looks really trick.   Where 
it differs from the transaxle is that it never lasts as long before 
failing.    But it looks nifty...
