Cobra Make, Engine: Still Working on This

Default Cold Starts

Still in the process this end of finding the perfect car and have a question regarding cold start of a few big block models I have looked at.

Have looked at three 427 type cars. Have noted that in all cases, when the cars were first started, i.e. they were still cold, keeping the engines running seemed to be a bit of a chore.

I have a 1976 TR-6 that seems to overcome this problem via use of a manual choke. Does anyone know if original Shelby's were equipped with any type of choke (manual or automatic)? I suspect that another route would be to equip the engine with fuel injection...

Interested in how others have gotten around this or do most see it as just part of the mystique?

As always, appreciate member inputs.

Bob

Bob,
Any carb'd engine with an aftermarket camshaft and intake manifold designed to run cooler for better performance will tend to be cold-blooded. Many aftermarket or performance carbs do not have the provisions for a choke or are adjusted to be OFF very quickly - again performance related.

In the end it is easier to peddle the car a little until warm than change plugs that are fouled from aggressive choke settings and big cams. Just part of the nature of the beast but not all engines or set ups have this issue. Learn to peddle the car long enough to warm her up or buy a less spirited engine combo or add a choke are all options for you. Yes injection will control idle electronically if that is your choice. ENJOY what ever ya get.

It's not just carbed cars that are particular. I have a FI car and it is still a little finicky. I learned that you have to start it without toutching the gas for about 1 minute. If you give it to much fuel it will run rough for a long time. Each engine has a mind of it's own and likes things to be done a certain way. Remind any one of anything
