Thanks I'll machine one out of 1/2" plastic stock. That will give an oppertunity to rotate the carb so that I get a striaght shot to the servo.

So, the location of the port that connects pulse hole of the carb does not matter? Would it work out to make a notch or furrow that connects the carb port to the intake plenum?

I just thought of this. Plastic cutting boards might make good intake manifold stock. I tend to use my bandsaw, drill press and dremil for these things. A forsner bit cuts plastic real clean.
