Gary, I took it apart today, I was concerned because it had an old GP-Sorensen kit in it and the needles and seats those used were famous for stripping the bowls but they were fine.

I have one of those Summit carbs. And it has the same booster cluster(S) as the Autolite 4100. Only real differences are it uses all common Holley tuning parts, has center hung floats from the top and uses the typical Holley acclerator pump. Runs like a clock. It's a Holley 4010 that's had the bugs worked out of it, is what it really is.

Which means the *only* perfect carburetor is the FORD Autolite 2100/Motorcraft 2150 2V and the Autolite 4100 4V. And that is why my 1985 Ford F150 Lariat has an Autolite 4100. :) |

That's correct. The Summit Racing Carburetor is the old Holley 4010 design (which was itself directly based off of the Ford Autolite 4100) that has been improved. There are no gaskets below fuel level to leak like the typical Holley design. And thanks to the annular boosters, throttle response and efficiency are both excellent. I think they are a good choice if you are going to by a new carburetor and drveability is important.
These carburetors have an electric choke. Electric chokes work "okay." They just work on a timer that has absolutely nothing to do with what the engine actually needs. By design, sometimes the choke will come off too soon, and other times the choke will turn on when the engine doesn't need it all. Therefore, driveability is just not going to be as good and smooth as a carburetor equipped with a thermostatic "hot air" choke.

Try running the Holley choke off the stator lead, it's 7 volts rather than 14.

Carterbrocks seem to do well with the e-choke. And while I agree the hot-air choke has the potential to provide a more accurate choke operation, millions of cars were sent out with e-chokes and worked well.
Sounds like the Summit carb isn't what I'm looking for since the choke doesn't work. Thanks, Matthew. You may have saved me some grief. ;) |

I've not run across that kit. In fact, I learned long ago to stay with Holley kits for them. The one I had on the original Super Bee blew power valves and had bowl gaskets leaking so frequently that I was always putting a kit in it. Once, and only once, I used a off-brand kit and discovered the hard way that the metering body gasket only had an accelerator pump hole on one side. So, if you put it in the wrong way 'round, as I did, you had no accelerator pump. And when it got cold it refused to start. |

You may have saved me some grief. ;) For what it's worth, I remember Chris complaining about the same thing with the 670 Truck Avenger carb he has. Comes off too fast and comes back on too fast. But, if he see's this. He can tell you himself. As I don't really remember all what he said. But I remember that. |

BINGO with the electric choke. I hate mine, that's the only thing I can say I really liked about my Edelbrock AFB better than the Holley, is the electric choke on the Edelbrock came off slower, and didn't come back on near as fast as the Holley. It was also more gradual for coming off. The Holley starts on the highest idle cam and when you go to kick it off 10 seconds later to the next lowest position it's all the way at the hot idle setting, no matter then choke tension setting. I'm converting mine to manual choke using one of the generic manual choke kits. I'd rather control it myself anyways, plus I'm the only one who ever drives it.

Does anyone know if the 2150/4100 hot air choke could be adapted to the Summit carb. If it is basically a rework of the 4100, it might be possible to use the choke set-up from a 2150/4100 to get "the best of both worlds", so to speak.
I had planned to look into the Summit carb. later on and since my Edelbrock manifold has the provision for the "choke stove" it sure would be nice to use it. Of course Summit couldn't build them that way since only Fords would be set up right. |
I don't know if the hot-air choke can be adapted, but if so the carb would have to be jetted slightly richer to account for the constant air leak the choke introduces.
Here are a couple of shots of the hot-air choke on the 2150 from Dad's truck. perhaps Matthew can tell us if it looks like it might bolt on. https://cimg3.ibsrv.net/gimg/www.for...615472f03d.jpg https://cimg4.ibsrv.net/gimg/www.for...3ca0c43f48.jpg |
And, by the way, the 1981 EVTM says:
The 12-volt all-electric Choke Heater has two ceramic heating pills. The first pill is always on when the engine is running. The second heating pill operates above 60 degrees F to open the bimetal at a faster rate. |
