Re: Is there a way to make a Holley less cold natured?

I had a 650 DP before I switched over to EFI. It was always really cold on start ups, even in the summer, but not as bad. I normally would pump the pedal 3 times, then crank it over. Typically would work well, but I would have to hold my foot on the gas for a minute or two. I had a manual choke hooked up, but it would get stuck, causing the motor to be choked when driving around. Hence why I stopped using it...

It's why so many young boys didn't go blind, but needed glasses at an early age........

Re: Is there a way to make a Holley less cold natured?

If your running an HEI it has about 17-23* f mechanical advance. As stated above you need more initial advance, try 16*. Also make sure your HEI has full battery voltage connected, no resistance wire. In addition make sure the HEI has voltage during cranking. The old saying that most carb problems are ignition related is true. You should have no trouble starting the engine with no choke other than having to maintain idle with your foot.

Your just jealous because you can't hear the voices!

X3 on more initial timing. 10 BTDC is not even for anything other than an absolutely stock cam.

I've run Holley's and Eddy's with no choke. For really really cold starts you need a choke. For everything else you can sit with it and warm it up with your foot without a choke A properly tuned choke will allow you to start, warm up, idle down and drive with very little effort. It's worth the investment in parts and investment in time to tune it.
