You need to find out how far off it 'really' is.

I bought an 86 with 31's on it and when I went to 33's the spedo became
accurate with my GPS on many tests. Have no idea what spedo gear was in
there.

You can just buy new gears for the tranny end of the spedo cable.

Emissions removed, oh oh....

Some of the 'emissions' stuff like the charcoal canister are needed.
That is the air vent for the gas tank and carb float bowl. If it was
removed and the lines blocked, then a vacuum will build up in the gas
tank and float bowl and it will bog down big time and even act like it
is running out of gas sometimes.

If you remove the emissions and don't kill the computer, it will go into
'limp home mode' and clamp down on the timing and carb mixture so it
runs like a bag of dirt.

It is easy to kill the computer, I just add two new wires and hook the
orange and purple wires at the ignition module way down under the washer
bottle to the orange and purple at the distributor.

You then need to reset the timing, it will have jumped and set the carb
mix up manually.

Here is a link on it:

Once the computer is dead, try high octane gas. I get an extra 100
miles per tank on high test vs regular 87 octane and a serious power
boost.

My owners manual even recommends high test if running loaded or hard and
hot.

If it doesn't idle smooth, there are fixes for that, that canister for
one. A kit for that carb is only twenty bucks or so too.

Oh with 32" tires, forget 5th gear or overdrive unless it has been
regeared. I 'can' run in overdrive on the highway, but my revs are too
low so it sucks gas and is boggy. If I stay in 4th at 2300 rpm, I get
19 US mpg highway with tons of power.

I just bought a 86 cj7 off a friend and was wondering if anyone could help
me out here? the jeep has 32" tire on it and I'm pretty sure it has the
stock gears in it and the speedometer is not accurate. how can I correct
this? also all the emissions has been removed and the carb just seems to be
lame. anyone have any recommendations for and after market carb? the 258
motor was just rebuilt to stock specs and it does not have header or any
other mods. carmine
