New Tool for the group

Ok....once again not much activity on the site. So, I feel compelled to come up with something.
As time has gone on sense the dyno day. I am still having trouble with dark spark plugs. Not all of them just some of them.
I have sent emails to Elderbrock tech about the distribution problem as not all of the plugs are dark...some of them look ok. The first answer I got is that my engine is the largest that they have documented using the RPM Air Gap intake manifold.....woohoo.
Of the possible things to be causing my rich condition. They mentioned the manifold might be too small for the cubic inch of the motor. Now I know that my heads are small for the displacement...195cc intake runners, and the intake is small according to Elderbrock, but to be honest I can't see how that would darken up the plugs.
The tech also mentioned that maybe the intake gaskets are not sealing, and it is pulling oil from the lifter valley.
As that seemed a reasonable possibility, I decided to see how to test it.
So I looked to youTube and found a smoke generator project.....here it is.

The results are in the video if nothing else we now have a smoke machine if anyone needs to use one.... just let me know.
