86 CJ7 4.2L, MC2100
Now that it's running and the lights and guages work, I have a new issue. The jeep sat for about 2 years and I never started it or anything.
I have put new plugs, cap and rotor in.
I was stupid and didn't check the timing and ran it with timing at >20* BTDC for a day.. I thought it was just running bad from sitting up, but it didn't go away. I set the timing at 8* BTDC.
Ran a little better, but still felt like I was missing a cylinder. So I pulled the new plugs out to check their condition and #2 and #3 were gas soaked and burned.
I checked, and have strong spark on all cylinders.
So I thought maybe having the timing so far off fouled the plugs, so I replaced the bad ones with new ones again. (Now that the timing is set)
Ran like a champ.
For 3 minutes. Runs like crap again.
I had to put it down at the time but am going to do a compression test when I get home tonight. Any thoughts or advice? I'm thinkng stuck valve. And I have never rebuilt a valvetrain by myself.
Thanks in advance,
Kevin
