After installing the K&N flowcontrol I now have this dead spot. Heres what it does, when I am cruising 2000-2500 and I just give it a little bit of gas it doesnt just go, it hesitates and goes dead for a second then goes.

It ran fine before. It says on the instructions you may need a 2 jet increase but Thats not where the stumble is??

Will just changing to a K & N air filter lean a carb out on Idle? My 3310 -3 780 cfm Holley runs rich at Idle but it runs fine every where else. Thanks Johnny

How big is the cam Johny? Is the primary blades not into the transition slots over .040"? Power valve not blown? Idle mixture screws do much when adjusting them? Some things to look at. Galen

Idling too high for one thing, and possibly the filter top is too close to the top of the carb. Idle mixture would be rich from the throttle plate position you now have.

Lower idle to 675 to 725 or so, then reset the mixture screws. They want to be close to 1-1/4 to 1-1/2 turns, any different setting and the idle circuit is being adversely affected by throttle position at idle or the idle fuel oriface sizing.

High flow air filter element shouldn't have an influence on idle speed or quality. Off idle, mid-range, top end would be affected.

Thanks Ignition Man,I'll try that tommorrow morning. Idle is a little rough lower than 850 to 900 but maybe resetting the idle mixture screws will help that too. Sure do wish that you were in eastern ky.

ing. mans answer sure sounds like the right one to me but have you thought about what type of oil you used on the filter dont those filters use a thin oil on them after you clean them like a dirt bike I know when I raced bikes if I used the wrong type oil or to much it would really restrict the flow I would check manufactors instructions for the correct type "fish oil"
