Re: Factory Tack Problem

Sits at zero at idle? I guess I would take it out and hook it up directly and see if it then reads right. If so,track down the bad connection,if not find out what dirt etc.got blown into the delicate mechanism.I'd study it closely and shoot some air at key locations. I don't remember mine having an adjustment in the back,you sure it's factory?-Brian
