Tachometers!!

Has anyone ever had 1 rpm gauge read 2k and the other read about 3-4 hundred higher with the throttles even?
This happens wether just going at idle or under cruising speeds!

i believe the gauges never lie.

but i would tap the glass first, and see if it knocks down.

The other possibility is , your engine coupler is slipping and you are in fact have one engine turning faster and doing nothing.

on a 95 i could believe it.

so go to auto zone and connect the two tach wires on a new $19 tach, and run them both together and see if the autozone tach read correctly.

Thanks for $ 20 bucks I'll definitely try it!

By throttles even, do you mean the levers? The cables may be slightly out of adjustment. On my 95 3200 scr, if I have the levers equal, the rpms dont exactly match, so my levers are slightly cockeyed. I just deal with it.
