A while back the hose to the oil pressure sensor blew a leak & oil got all over that side so the distributor and everything over there got pretty much soaked in oil.
I have no idea if this is related to that, but it has started running rough, especially when cold. This started showing as reluctance to start at all when cold. It eventually did start but then sputtered and popped especially if I tried to drive it before warming up a lot.
What I tried:
Pulled plugs, cleaned them. All but #1 appear to show a overly rich mixture while #1 was just about right for plugs that were replaced a little over a year ago.
Removed blue snap together wire connectors the PO attached to lengthen the wires to the coil and the side of the distributor.
Put on a new female connector for the wire on the side of the dist and made a better connection for the coil.
Noticed the top of the coil seems a tad bit loose - is this a problem?
Opened up dist cap & made sure contacts were clean, scraped off a bit of scale from the aluminum contacts inside & shined up the edge of the rotor.
Screwed in the adjusters on the carbs and then opened them up 12 faces each. Tried running, still pretty rough. Opened them up one face at a time on each down to 16 and it was just getting worse, ran them back up to ten and it seemed to smooth out there. Adjusted idle.
After this the car ran & drove good, lots of power & no backfiring. (it was warmed up)
This morning, back to sputtering and popping.
Until it warmed up - then it ran pretty smoothly.
I plan to check the timing next. Any other thoughts?
