Default 1966 tri power choke pull off

Could a faulty pull off cause restarting as well.

Thanks in advance.

Default Choke pull off

Engine is at operating temperature and switched off. Hard to start five minutes later. Thanks.

The choke pull-off is only used to open choke blade some at cold start.
With hot engine, no choke, no choke pull-off.

Using a mech fuel pump (with check valve) and fuel line close to hot engine parts fuel pressure rises to a point where inlet needles leaks and raw fuel dribbles down into intake making hot starts after 5-30 minutes hard.

Fuel filter with return line to the tank or/and usage of an electric fuel pump mounted close to the tank bypassing the mech pump eliminates the issue.

Hope this helps some.

X2 on post by Kenth now that I understand your carb issue.
I had special heat insulators under my Rochester Tri-power Carbs for many years in the 1960s. Helped in the Missouri summers.
