What is the procedure for adjusting the idle mixture screws? Does it start with a certain number of turns out? Want to try tuning out a faint put put sound.

First, remove the screws and make sure they are not rubber tipped. Use solid brass screws. Then screw all the way in gently and back off 3/4 to 1 turn. That should do it. John

you really need a vacuumn gauge.to do it right, usually you turn the mixture scews in till you get a stumble, then back out 1/4 turn or so till it smooths out,the vac gauge should be read fairly steady and be around 20.or so, you might have to go back and forth between the 2 screws till it is adjusted. what year car and what engine,???? you might have to adjust the timing in 49 and up engines, If the idle is not smooth, take a compression test, so you know the valves are good, the compression should be fairly even, hope this helps 37 RAGTOPMAN KEEP ON TRUCKIN,,,,!!!!

Hey Ragtop, Heading to Nova Scotia this weekend in our 46. If I see the lighthouses on RT 1 we will stop for a quick h*llo. John
