Adjusting the Idle Mixture Screws

The idle mixture screws only affects idle. They simply control the amount of fuel and air mixture that is delivered at idle.

First run the screws in all the way until they seat, lightly. Too hard and you will damage the screw. Now back the screw out until the specified rpm is achieved. Turning the idle mixture screws clockwise (in) leans the idle mixture. Turning the idle mixture screws counter clockwise (out) richens the mixture.

Turn the mixture screws, alternating between the two in 1/4 turn at a time until the engine rpm starts to drop, then turn them back out 1/4 of a turn.

When adjusting your idle mixture screws doesn't seem to change the engine rpm much is an indication that there is something wrong and could be an indication of a needed rebuild.

Idle mixture screws

I can't say enough good things about the crew at Mike's! I bought a '67 Mustang with a swapped engine and no documentation. The idle mix screws on the carb were clearly bent and kept the engine from starting / running well. I saw some of their videos on YouTube so I asked for help. 1) The team emailed me back right away with helpful answers. 2) They helped me find the right screws the first time. 3) They shipped my order the same day and I received them lightning fast. Any time I need something for my carb, I'm going to Mike's first.

Still Works great

Great service and prompt shipment, unfortunately I ordered the wrong one, still works on the carb I currently have in my truck but been thinking to upgrade with an intake and edelbrock carburator.

THANKS!!

Thank you very much for a most speedy delivery, which arrived today, Tuesday. Certainly much faster than some local deliveries here in the UK! Thanks again, I am sure that I will need a few more parts for my Tiger Resto in the future, certainly a new or s/h choke housing for a 2100? Chris
