Speedometer Change

[gene]

Anyone see a speedometer work, but sluggish as heck? I installed a 79' 140mph on my 1980 XS and it's way off. I was sitting still and it was still reading 30 mph. It drops to zero, but it takes awhile.

Yes, I had one like that that eventually started working right.

Thanks Skids. I'll put some miles on it and see what happens.
