1982 911SC Hot Start Issues

Recommended Posts

Runs perfect , drive in hot day 85+ degrees, stop for 30 min or longer and does not want to easily start (takes 10+ seconds of cranking - seems to starving for fuel)
Replaced fuel pump, check valve and fuel accumulator.
Didn’t cure the problem.
Any expert suggestions??
Thanks.

Are you sure it is starving and not flooded?

A leaking cold start valve will cause starting issues.

 

Try starting with the accelerator pedal to floor...

I don't smell gas and stepping about halfway on the gas pedal helps it start .
Yesterday after starting for the first minute or so it's rough and doesn't want to idle nicely, that started just yesterday. After couple of minutes it's perfect again .
