Mystery3B problem (long)

[Ben Swann]

I don't buy it.  There are two cats - both clogged to the point of this sort of running.
That and the exhaust was checked.  Oh yeah, I forgot something else he told me - the
cats are punched out - so this is not the problem.

I'm looking more from the perspective, what was the last thing that was messed with, and
in this case a big way.  That would be the head was completely rebuilt.  

Don't know why the heads were rebuilt, presumably to solve this problem.  Presumably
perhaps because some one prior to that messed with the cams, and left others to deal
with the aftermath.

Just seeing if there is any other possibility.  I really shouldn't care, but being I let
myself get sucked into fixing other peoples cars, I want to make sure I'm spending my
time doing that wisely.  Not that fixing other peoples cars for cheap is a sane thing to
do in the first place, but I digress.

Given it doesn't like to rev, and there was heavy black exhaust when you could get it
to, my guess is still a clogged cat.

They say the problem persisted with the exhaust removed. But maybe the rich exhaust and
bad 02 was 1/2 the problem even with the exhaust removed.
And now with those problems fixed, the clogged cat can rear its ugly head.

Or go back to the basics -- air, fuel, compression, ignition: which one is playing hard
to get?]
