Hello Everybody,

I’m rebuilding a AUTOLITE 2100 that was removed from a 1967 mustang 2V automatic. It has the fuel bowl vent components and I’m wondering if I can eliminate these components altogether and if so how? Also, if I were to eliminate them would it be concours correct for 67? Here’s a link that contains a pic of the components I’m referring too (see 8th thread):

http://forums.vintage-mustang.com/vintage-mustang-forum/617731-need-autolite-2100-parts.html

Also, could someone confirm my suspicion that these components were added in 1967? I’m basing my suspicion on the pics in below Ebay links. Note how these components show up after 68. Could someone please set the record straight on this?

Finally, the reason I’m bringing this up is because I’m considering buying a re-manufactured carb and became confused when I started asking questions about whether or not to buy a carb with or without these parts.

Thanks in advance for answers and stay away from the 2 swipe diesel pump:bs:.

Some 67's had that vent seal, and some did not. The vent hole was drilled on top with it, and angled without. I'd say leave it alone. What year are you planning to put this carb on? What trans? Smog pump?

Its going in a 67 with C4. The car has the smog pump and smog exhaust manifold.

It was late 67 when the venting assemblies came into play. What are the nubers/letters on the toe of your carb? Was it original to the car? The little plug you see on the top of some carbs is the cheesy block off that some rebuilders use to avoid having to deal with those pieces. The little stopper comes in the kit, but the other parts may have been gone when they got the core. When was your car made? All that thing does is keep the fumes from smelling up your engine well when your foot is off the gas pedal. The bowl needs a vent for the fuel bowl. As said, earlier, it was just a small hole on the angled face of that boss until late 67.

The numbers on the carb are 7D V. It came off the car and I'm pretty sure its the orginal. The car is a late build california car.

Yes it had those parts. I have them from a couple of 68's I turned into a tripower setup. Let me know if you want them.

Hello please help

I new to rebuilding carbs. I also have the autolite 2100 and I'm having issues. After I rebuilt the carb and finally got it started.... it first had a blow back issue. (Small fire in the carb) now since I got that under control it either run at a high idle or very hard.... please help.

1. Get a factory shop manual. Some people prefer the CD's. It's an invaluable source.
2. Set up the carb as described in the Fuel section. Pay particular attention to how the choke is setup.

High idle is usually indicative of the idle circuit not operating correctly or being bypassed by the throttle plates being too far open when the linkage is at 'rest.'

Welcome to the forum! Some really great people here with lots of knowledge and insight. Start a new thread with a title like 'Fresh 2100 rebuild issues.' Some people won't make it too far in an old thread and it's best to state what the problem is instead of tagging along on a different subject. Also, what year car you are working on and a filled out bio (I did not check to see if yours was, just a statement in general) will get you more specific answers and possibly some local help.
