Just for your info as well, I run a 38mm choke in my quad 44 IDF carbs on only a baby 308 cuber.

I should post a pic of the setup. They are on an Inglese intake that has a vacuum runner cast into the intake. So yes. And then running a PCV.
Butterflys are completely closed at idle and it runs at about 1000rpm. I actually like the idle a little lower but can not acomplish that without backing off the timing. The initial timing is already a little retarded for that cam.
I am going to try a few things this weekend and will post my findings. I am going to start by going back down to a 60 or 65 idle jet and pull the mains to make sure they are not influencing anything to start. My rpm pickup for the LM1 died, so I may not get much useful info logged until it gets repaired.
I will let you guys know. Thanks again for the help.
