Edelbrock carb adjustment

Yes!. Car idled and ran better with the 800 AVS I put on it out of frustration while trying to clean up the idle on a 4 corner 750 carb with quick fuel metering blocks. I didn't pursue the Holley after that because I was so surprised by how the AVS ran.

Funny, I plopped a 69 HP 440 AVS on my brothers 289 while I was "tuning" his Holley again. Finished the Holley and went to swap it back on the Mustang, and he told me to sell it, he wasn't giving the Carter AVS back. That carb has sent many a Holley to eBay heaven. I'll buy that carb every chance I get.
