Yes, either idle mixture screw will stall the engine if it's screwed in.

It's a stock 5.9 Magnum with the original fuel injected camshaft. Vacuum is unbelieveably high.
Well into the teens, even at speed.

The throttle response is excellent. In fact it runs great and the power is up. Besides the fact my mileage is history and I"m suspicious something is defective in the carb making me run such a small jet and so little mixture screw. I'm a happy customer.

In this vid you can see the throttle response. Off idle to WOT with the clutch fully engaged.



If your happy with it, i'd say just suck up the mileage loss & have fun, another thing you should remember is in "most" cases a larger cfm carb will use more fuel.
