Thanks Hop! Anything you suggest to plug those bastards. I was wondering why my idle was so high.
I've been using a length of fuel line, which runs from one barb to the other barb,with small clamps on each. I've tried using rubber vacuum caps that are sold in automotive supply stores, but they don't last very long..................all too soon they crack and air leaks cause idle to wander again.
The fuel line is much more robust, and lasts very well. IIRC its 3/16" fuel line.
