ummm...turn down your idle screw? that's a good fix. sorta hard to get to but it'll fix your idle problem.

If you have a dremel tool or something similar it makes it a lot easier

the only problem is when i look at the idle screw there is a gap and it doesnt look like its going to go away

i think i had the same problem. i had to shim the pin where the two springs ride on (the pin is wore plum out) after i done this it let the idle spring release tension and would idle down.

i guess im not sure what pin your talking about is it actually down in the pump?

On top. There are 2 throttle levers with a spring between them. It's an over load device, if the throttle goes too far, it won't over load the pump shaft. 1 lever is hooked to the throttle, the spring connects the 2 and the 2nd one drives the pump shaft. The pins the spring rides on wear, letting things get loose. The spring wears too.
Just look at the lever on the pump, and turn it, you will see what we are talking about.
