Sudden extreme rich condition

<< < (6/7) > >>

73ss:
It could be the oil pressure sending unit. There should be one above the oil filter. It allows current to the choke when there is oil pressure. Does the car have the choke/oil light? I had one fail once. Jumped it out.

MP81:
It does have the oil light on - coincidentally...that came on when the speedo cable detached, and all this started...I have oil on the dipstick (it doesn't leak any) and I'm pretty sure the engine would have seized by now if it actually had zero pressure...

73ss:
most likely the problem. You might have dis-connected it when messing with the speedo cable..

MP81:
That would explain a lot - it's pretty nice out, I'll give that a look at today.

MP81:
So my sending unit is up next to the distributor and the connection seems wayyyy looser than one would expect. It doesn't seem to snap down all the way, not sure how it would have done that on its own, but its 36 years old, so...I won't question it, haha.

I'm currently double checking that it is not intended to be that way, but it sure seems like that could be my culprit...
