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.

The machining on the screws is excellent and they fit perfectly. I was impressed by the finish and fit.

Mixture screws

Abolutely identical to the parts I was replaceing. The website was easy to manuever and the shipping was expediant. Most importantly, the order was correct. I have had difficulty getting my order correct and quickly from a competing vendor.

Rochester 2-Jet mixture screws

Unfortunately these needle valves are the wrong length for my Rochester 2g tri power set-up. They appear to be very high quality. I guess they are going to look nice hanging on my garage wall.

Good Idle Mixture Screws

Wasn't able to find any auto parts stores around (I checked about four different chains) that stocked these screws or even was able to order them. Mike's is the place to go!
