Hi guys and Jeephammer...I've read and re-read the teamrush and this thread several times. I live outside the U.S. so getting the parts and accesories is very tough for me, but my 83 CJ7 258 hopefully will be with me for years to come, so I'm trying to do everything right.
I team-rushed with Bosch cables, the Ford cap, new rotor, imported di-electric grease and never-sieze. I am not mechanically intelligent, but I work with my local mechanic, using the forum and translating everything for him.
I had motorcraft plugs for the last 4 years, but recently one fouled and I decided it was finally time to install the new autolite plugs that were recommended in the teamrush thread. I gapped them at .044 and decided to finally install my E-Core coil bought from Summit. Jeep lost power and my mechanic was convinced that the bigger gap plus coil had been too much for the factory module, so we installed the summit cdi.
The Jeep starts like never before...and it idles great. But around what I guess is 2000-3000 rpm (the tach stopped working with the cdi box and it takes a while to import new stuff) starts misfiring. We've tried to adjust timing, move the timing advance vacuum hoses from the carb, remove them, etc. but we can't get the Jeep to run well. It doesn't have much power. My mechanic had the Jeep for the last couple days and told me the only thing he can figure out is that the distributor is failing. He says it's not in very good shape. It seems to be the original, now 30 years old. So here are my questions:
1. Should I get buy an new distributor, and if so, should I stick with a rebuilt cardone, factory, or invest in something like the summit model for $150? Seems like JH says factory. Is this it? http://www.summitracing.com/parts/AAZ-30-4691/?rtype=10
2. The harmonic balancer is worn out, in bad shape, doesn't show TDC. Should I get a new one, if so, which one do you recommend? Dorman? Omix? Crown? Should I buy the MSD timing tape kit for it, or does it come with that? Do I need to buy a harmonic balancer puller? Which do you recommend?
3. I'm going to buy and install the OEM tachometer. With the summit box that I have SUM-850610 (I took it apart and the guts have the MSD logo!) which tach adapter will I need?
4. Based on other stuff I've described, do you guys have any other recommendations? I really appreciate it, I know everyone is busy and responding to this is a time investment, but I really need help and hopefully your response will help others in the future!
