Hi guys new to the site here and want to give all a big thanks for all the info out there. But I have ran across a problem that I need help on.
My problem is my jeep when cranking performs like it is out of time or has a weak starter once started she runs and idels very well no other problems.
Here is what I have done so far:
1988 Wrangler 4.2 Standard
Oil and Filter change
Nutter Bypass ( Ran a seperate Ground )
Team Rush Upgrade
Plugs and wires
MC 2150 carb ( Air Filter )
New Starter ( Ran a seperate Ground to Starter )
Checked for vac leaks and repaired
Set timing 10 BTDC Tried at 1600 RPM and at 650 (Had Vac line off and plugged while setting) Ended up going 12 BTDC to smooth things out.
Ran Compression Check on cylinders
Sory I have replaced the cabels, Load tested the new bat held 11 volts under full load even tuck the bat out of the truck to double check, could the distributor be out just enough to make hard cranking but let her run good after started?
11 is low. What is the reading at the battery with the engine running. Sounds like the alternator might not be putting out enough juice.
Without the engine running 11 is not low under load test. Now below 9 is low under a full load test. This is how you test a battery.
What is the voltage before and after the load test. Without the engine running.
Sound like your timing is out and if I remember it should be 7* Not 10* at idle.
A 89 yj with a 4.0 aw4 sye out of an 92xj. Now the hard part is done time to get it up in the air just a bit. Working on 8.8 with 3.73 and lsd for the rear. and new D30 hp with 3.73 .
For those who have not figured this out I'm old school but can handle the new too.
