Thanks for the advice guys. The compression is not in LBS. Not sure what unit of measure, probably metric. I spoke to a few guys who are mechanics and they say that it is perfect. They also mentioned that if a valve was not sealing or seating correctly I would have a much lower reading at that piston. So their conclusion was that the valves may be too tight.

Ok I don't know Jack Benny either. Will try and get the book you mention. Thanks for explaining the higher vac port. Makes more sense now.

I'm sure my issue is with the carb. Carb specialist where I live want almost the price of what one would pay for a new one to overhaul.

Are you guys dead against a weber. I have already committed to it and should be with me soon. At a recent car show in my town I met a guy who had the same motor as me but did the carb conversion I want to do and this guy could not stop talking about how good the conversion setup was. He mentioned that it gives better gas mileage and has a bit more legs.
