[T3] New Distributor Same Results, 034

[Craigs List]

"I sure you have check but have you verified that there are now vacuum
leaks in the intake system?"

To the best of my knowledge I have the intake system sealed 100%. At one
time, when I had the 40's on there, I did have a vacuum leak. Most vacuum
leaks that I have ever dealt with make adjusting idle a pain in the ass,
and effect the idle on cold starts. I do not have any of those ill effects
that would make me thing that I have a vacuum leak now.

Maybe under load I am getting a vacuum leak somewhere? That would cause it
to bog, but I would assume that it would also cause it to lean out and
backfire if this was the case? I do not have any backfiring.

One more option is to get a bung drilled into my exhaust after the
collector. Then I could use an LM1 I have available and see exactly what I
am dealing with as far as fuel at acceleration. I just do not think it is a
carb issue, but I am chasing everything at this point.
