1993 Jeep YJ, Checking the Timing, Full HD Video on this one! 

One thing to keep in mind is, depending on how a vehicle has been driven/maintained, the harmonic balancer can become displaced from its original position on the crank. In turn, putting your timing marks on the pully off. This is what happened with my jeep 4.0 and the only fix was a new harmonic balancer. Just something to consider...

The base timing is supposed to be like 8-10 . Overall timing is much higher like you saw. Remember on the old vacuum advance distributors, to set base timing you had to unplug the vacuum line to check it and set it. Old Fords (my '89 for example) that were fuel injected had what was called a SPOUT connector, just a jumper block you unplugged to set base timing. I'm sure Jeeps have something along those lines. I just got a '92 Wrangler so I'm learning myself.

Hello, I’m TC. Retired mechanic. I hope the timing fixes your problem. If not check fuel pressure. Just one psi out of tolerance can cause a miss like feeling or a surge. Hope this helps

I was curious if you had fixed the timing issue because i believe mine may be bad due to the same type of distributor problem.

What’s correct degree?
