HELP. I have a 1974 Roadrunner with a 318 engine. Originally an automatic NON air-condition car. Currently it is a 4 speed and has after market air. My problem is when i turn the AC on it draws the rpm down and sometimes even enough to stall. Have checked for Vacuum leaks, replaced the vacuum lines with new ones with no help. Any suggestions. A new distributor with a new vacuum advance, A TIC valve that appears to have been on cars with AC from factory which mine does not have, or is it a matter of carburetor tweaking. Thanks.
