John,

Thanks for the comments. Virgil seconded your comment on a "pointless" ignition.

The manifold direction is what I had planned and I appreciate the "heads up" on the difference in thickness. I was curious about the carb heat business. I remember that from my youth working with old American cars that often had "heat risers" in the exhaust systems.

I follow your explanation of the crankcase vent and will probably do what you suggest. That inlet on the intake manifold is about 1/4" ID and I wonder about the amount of air going through it during idle/decelleration. I wonder if it would be better with either a smaller orfice a PCV valve in there somewhere. We'll try it and see.

Thanks again for the comments.
