Phazer carb

On my '88 Phazer carbs, there is two mixture screws on the top of the motor end of the carb. The owners manuel says that they are for adjusting the jetting for altitude and temp. changes. I was wondering how much these will adjust the mixture. I've turned them a full turn past factory settings to the richer and it still wants to run a tad lean and I don't know if I should just keep turning it out or if I should just rejet.

thanks

If I'm not mistaken, those screws are the air adjustment screws. They will have minimal effect on the rich/lean setting of your engine. If you are changing altitude, you will need to change the main jets.

The manuel calls them pilot screws. It says to adjust them for altitude and temp changes.

Re: Phazer carb

The screws you are talking about are opposite that of a slide valve mikuni, if you let them out, your mixture is richer, if you move them in, your mixture is leaner, I have to adjust the my daughters piped phazer quite regularly. It runs quite different in the fall verses the spring, and if I don't make adjustments it tends to just not run well.
