Thanks for your help.
I have read almost all the posts about this, and still have questions. But I know it is hard to explain things over a post in the internet.
Since I drive very often up and down I-95 (from Florida to NY), one day I'll try to contact you when I am in FL, perhaps we can talk over a cold one.
Hopefully this weekend I'll pop the hood, take the air filter out, and play with the screw until I get the 50% duty cycle.
For me is hard to work on the car, since I live in an apartment complex where it is a big NO-NO to do mechanical work in the parking area. They only allow things like working on flat tires.
So I take a couple of tires OFF and open the hood
I can't wait to own a house with a garage.
