3B motor bucking update - solved

[Mike Sylvester]

Brandon,

I think you may have solved my problem as well.
My grounds are tight, I've checked them more than once when dealing with
this, however it just dawned on me...
My intake manifold is powder coated.
My grounds are probably making good contact to the manifold however the
manifold is probably isolated from the head.
The gasket is non-conductive and now the bolt heads don't make good
contact.

Unfortunately, I won't know if my problem is solved until the spring.
