The main problem you might get is hard starting in the morning if the weather throws you a cold snap. You won't see any difference after the car is warmed up.

I hate my electric choke. Hot air or manual chokes work better. I've currently got my electric choke disabled, but I think I'm just going to cut the air horn off and keep the throttle half functional.

Holley electric chokes do 4 things 1) richen the mixture for cold starts, 2) increase idle speed 3) limit full throttle 4) re-engage too quickly after a short shutoff. I think this is true of all electrics, I prefer intake manifold chokes. I just removed mine. All you need to do is hold a high idle for about 1 min on cold startups without it.
BTW, if you remove it, remember to plug the air bleed hole on the side of the carb.

After dealing with an electric choke for two years and getting fed up with having to open the hood and adjust it every time I stopped at a gas station, I went with a mechanical choke on my Demon 650.

It's the convenience / peace of mind that came from riding motorcycles and having that direct mechanical control of the choke horn that finally convinced me.

As an ignorant noob I owned my 68 for over a year when my mechanic mentioned to me that my Qjet choke was jammed open and I was missing the parts to make it work. Well, if the parts aren't there, how am I supposed to know what they look like!

After studying some books and catalogs I finally figured out what a "divorced choke
was!

I was missing all of the divorced part. My new carb has fully fundtional choke and works much better, but the point of the story is I didn't really miss it when I didn't know I didn't have it!!

I have a Holley 650 DP with the added electric choke kit. It did not come with enough instructions for you to set it perfectly so you have to do trial and error for a while in order to get it dialed in. I added the electric heat sensor option and it seems to help a little.

One thing I do on restarts if the engine is warm but the choke coil has cooled off is to turn the key "on" for a little while before cranking. The choke coil will heat up but the engine is not running so there is no vacuum draft inside the coil housing. Normally, the vacuum bleeds into the coil housing to keep the coil from overheating during driving. The lack of air flow with the engine off causes the coil to heat up faster and then the choke opens faster.
