Thanks Bill.I now have it set on the ball but it made no difference.

KL may have hit the nail on the head unless I have a bad vacuum leak I can’t find.

I removed the filter and blocked off 3/4 of the air intake with my hand. When I do this I can set the idle way down and it idles smoothly.

Can float level cause my problem?
