Chokes on a old car

My experience on chokes is that , the upper midwest has too rapidly changing weather. The electric choke you twist for the season climate condition, as long as the weather is similar the electric choke is fine. 3/4 of the midwest's year the temp swings more than +/-40 degrees day to day. Some mornings it will not start or function properly , because yesterday was 42 , today is -20 . Carbs mostly do not have IACs , IATs ,or MAP sensors to help cold start and idle.

for your consideration, give a manual choke a chance. They always work hooked up correctly. Never has the problem been the degree of choke, or duration. Anybody else feel that is a correct estimate of the situation ?

I agree with you partially.
To be able to use a manual choke, you have to know HOW to use it.

I have an old 1974 Ford pickup I use occasionally, and it has an electric choke on it. The choke heater is just wired up through a fuse, I pull when I park the truck. When it is cold, I set the choke, start the truck, let it warm a little, and plug the choke heater fuse in. I just leave it plugged in until I am done using the truck that day, and then I unplug it.

I disagree. Both hot air and electric chokes worked fine under those conditions when the vehicles were new and continue to work fine today when adjusted properly. At worst, I've had to make a seasonal adjustment to the choke coil, once before winter and once after winter. The problem is that with EFI, people are used to putting the car in drive immediately after starting it. With a carb and choke, it DOES pay to let the car warm up on fast idle for a minute or so.

Of course, the other problem is that these cars aren't new anymore, and there are a multitude of other problems that can cause poor running but that are covered up by use of the choke. I've run a maunal choke. I prefer a properly adjusted automatic one.

The only auto choke I've never had a problem with is the thermostatic type on the old Quadrajet's. I have a Holley now and the only option I have other than manual, is electric. We have big temp. swings here in Indiana too but not as long of a winter season. My choice here is manual as I have control over it. Works good for me on my 79 350.

I have had many carbed cars in the past (and still have two) with both thermo and electric chokes and have never had to make seasonal adjustments to them. I do remember having to vary the starting sequence/mehthod with major ambient temp changes. One of my current garage queens has a manual choke which I agree is the best.

I have a edelbrock with a manual choke that isnt hooked up, just open. The thing never has problems in cold weather. All i gotta do is pump the gas 2 or 3 times and start it, and depending on how cold it is i may have to hold the rpms up for a few seconds. Never tried the choke though, it would probably fix this.

LMAO,
Seriously ! you think there is a big learning curve on this? About the first time you flood the thing you have learned all there is to know. Personally I like the manual choke cause it keeps the clutter down, my wife's hot rod truck has manual, she seems to get along with it just fine. Yeah they are real tricky to use, took me most of my life to get the hang of it.

I guess changing a flat tire would require some sort of vocational education.

Don't laugh too hard. My mama taught me how to change a tire with the tightening sequence that even apply's to 6-8 lug wheels. At 16 yrs old, it came in quite handy with the college girl's that lived in the apartment complex
up the street from our house on the way to school OH YEAH!
