Don,
2 things I noticed on that dyno sheet...I've read repeatedly these engines are 7000 rpm with max power in the 6500 area.
This guy stopped the pull at 5800, did he say why?
Second is that it says it's pulling 1.3 inhg at 5800...If that is accurate, I'm going to stick my neck out and say your carburetors are too small and are choking it.
As to measuring the jets with pin gauges, I read somewhere that the numbers on the jet represent its size in MM...e.g. a 190 is 1.9mm.
