So I was installing a diff fuel guage since I wiped some of white graphics off the old one when I was cleaning it and when I put it all back together the tach wasn't working correctly, (%$#@)! Worked fine before, but now it sits at zero at idle (approx 500 rpm) and I'm guessing it lags about 500 rpms behind as I rev it up. I messed with the adjustment at the back and it will not correct it, though it does change how fast the needle moves across the gauge.

I did refinish the needles when it was apart and then blew the cluster out with some compressed air......I'm totally stumped and pissed too cuz it screwed up my planned progress today.

Just for more info, it is hooked up to my MSD tach output, but like I said before, it was working.

Any ideas?
