the chock must be bad.
on all carb cars , since 1964 i remove it and make it a manual choke
then hot starts are easy, hot, its not touched. (instant starts hot)
chokes this old never work right, t
hey are TOO old
the spring in side (bimetal) is NO GOOD. it fails to open properly.
try setting the choke calibration more lean.
if at higher altitude, even leaner.
the book is free. see it here

The choke is a device on most old carbs (varies by country)
that closes a butterfly valve, (google that) and starves the engine of air, thus the word "CHOKE" as in Choking it.
this causes higher venturi vacuum and more fuel flows from the jet nozzles.
if the chock is set too rich the engine floods
if set too lean , you have to pump the gas pedal to keep it alive.
if the bimetal spring is slow, it floods
if the choke is electic the heater needs to work or the choke sticks on.
if the choke is water heated, the water needs to flow there. again
the motor floods and stalls.
rtm. read the chapter on the Choke, the book is free.

I found by observing both of my samurais that the problem one did not have gas coming out at low rpm. I fashioned a spray tube and shot carb cleaner into the jet and it now runs great.thanks
