[Ben territory]

I have a TE with a XE falcon motor slightly worked i.e head port/ polish, crow cam, balanced, etc which does not like to cold start, getting worse over the years. Hot start is not an issue. Had two mechanic look at it, said carb is tuned and electronic choke is working well. Both charged over $150 just to look at. I pump throttle twice with ignition on, then flutter accelerator when turning over. I find it usually fires when after stop winning motor after 30 secs. It also back fires in carbie and smoke comes through air vent. Mechanics said I am starting it wrong, but I have owned this car for 20 years, so I think I know how to start it. Wondering if anybody had any ideas.
