Default 1966 Mustang Hi-Po Air Cleaner help

Hi Everyone,
I'm new to the forum and a new owner of a 1966 Mustang Coupe. I'm new to working on cars, but i'm learning a lot fast so i'm sorry if my question is dumb...

My car has less than 500 miles on the engine rebuild and has been running great. This weekend I decided to change out the stock air cleaner/filter and put on a scott drake concours Hi-Po blue base air cleaner. Shortly after I made the change I noticed that my car started sputtering while driving and eventually it died.

I was able to get the car home and the next day it started without any problem. It drove for a few minutes before dying while in motion. I was able to pull off the road and couldn't get it started again.

It seems pretty far fetched, but i'm wondering if this is related to the change in the air cleaner. When I made the change the car did seem to breathe a little easier but I have no idea. I don't know if any adjustments should be made to the carb or what...

the second time this happened I went home and got the old air cleaner and filter and changed it out and the car started after a couple of tries and ran without any problem.

I guess its much more likely to be some kind of ignition problem, but I have no idea... any help would be appreciated. Hope i can keep learning.

Look carefully at the stock air cleaner and see if there is a vacuum line attachment to it. As I recall this serves the choke heat tube. If you change the cleaner you have to make modifications to the automatic choke.

thanks Yadkin,
the stock cleaner and the new cleaner both have a breather tube that is capped. I'm pretty sure that is all i see.

It sounds to me that the choke is closed when the engine is cold so starts and runs, but does not open fully when warmed up so stalls out the engine. Check the operation with the old air cleaner installed, then let the engine cool down and compare that to then operation with the new cleaner installed.

The new cleaner may be creating less vacuum to the heat riser so it's not warming up the choke thermostatic spring as fast as with the old cleaner. This can be checked with a vacuum gauge. Connect a spare length of hose to the old cleaner vacuum port, install the cover, start the car up and test it. Then do the same with the new cleaner.

To adjust the choke a couple index movements of the choke thermostat towards "rich" may be all that is required. There is a chance however that you'll need to upgrade to an electric choke.

Thanks for the advice! I'm gonna give it a try. Sorry about the double post. didn't mean to do that...I was just trying to provide more information to what the problem could be. I'm moving this thread over.
