Is there anyone in the Sacramento, CA area with a running L-jet car? Are you willing to plug my ECU into your car to see if it works? I have a '74 with a pukegressive carb, and a box of L-jet parts. I think I have everything but the fuel pump, but I don't know why the PO removed the FI for the carb. I would hate to install everything only to find that the ECU was bad. Let me know if you can help. I live in Elk Grove, and work in Rancho Cordova.

Thanks

... the air flow meter has a rough/sticky spot at about 3/4 open.

Could be a warped flap. Most of them have a spring-loaded valve in the flap, but sometimes that isn't enough to let a backfire go through without causing damage. A big-enough backfire can warp the flap in the meter, which can cause it to stick.

Not sure what you'd use to seal it back up after you opened it. But any time you mess with the relationship between the return spring and the flap's shaft, you've altered the air/fuel relationship and you will probably have a lot of tweaking to do in order to get it right.
