What would cause a cold start issue?

Post  psfracer on May 9th 2012, 9:17 pm

Ok, so its 90 degrees out today, and after sitting a week, 1 pump of the accelerator and the car starts right up.

But November of last year, during the Street Car Super Nationals in Las Vegas, during the night it got cold (low 40s) and in the morning with it barely 50 degrees, the car was really hard to start. I am talking like 12 attempts before it finally started, then I had to feather the gas to keep it running.

What would cause that? Gas is Q16, plugs are NGK R5672A-10s (but also had the same problem with Autolite 3932s), gapped at .032, Kaase P51 heads.

Did you have the choke cable pulled out?

A buddy with a welding glove on serves well as a choke on chilly mornings

Sounds normal at that temp.
Need lots of fuel to fire and have to keep on the throttle till warm.

How do I know ? Try starting a 78 ford 460 with a 3310 holley in -30F without a choke in Alberta Canada LOL.

By the way I was down at Famosa Apr.21 and the wife almost got heat stroke on the tarmack at 98 F air temp.

X2,My car takes more pumps of the gas pedal to start in the cold then it does when it's warm out.

Later Mark.

Typically the COLD is the cause for cold starting issues. With that said, its the lack of a working choke if carbed.
