OK well I have tuned it further.. can't tell yet if it is any better but one thing I noticed is that I do not get a nice stream of fuel when I activate the fule pump and it certainly is not consistant between the two carbs which leads me to beleive that the linkage is not installed correctly. I think I also need hotter plugs. I currently have Bosch w7dc's so I'm going to try some NGK BP5ES or BP6ES.

The other thing that bothers me is that I still have a rough idle... can't seem to get rid of it ..maybe there is a leak in the manifold but I haven't been able to find it.
