My '79 MGB has this hose looks like this
(to metal pipe which goes to heater)

(to bottom of radiator)
Where the small part coming off the top was smaller in diameter than
the rest of the hose. The DPO had DUCT-TAPED the small connection where it
had split. I replace the hose with one from Moss for ~$12, I think.

Mine has a water controlled choke. The water warms a spring which
closes the choke as the water gets warmer.
