Thank you very much Tony. Although I may not live in the mentioned states, but I live in Las Vegas NV. Ambient average temps hover around 100deg for a few mounths here and many nights so hot the temps dont drop below 90deg. Im not going to change over to the Mikuinis. So, I will have to keep an eye on my over all design with a fuel return line and before carb regulator.
So this does bring up another question as to were to mount my heat shield. I'm looking at attaching it to my manifold. I have seen peapole attach it to the carbs, then I have seen some new ones that attached to the bottom of each carb?
