Another thing to check

Rob,
It is possible that the advance mechanism in your distributor is frozen. If this is the case your engine will start normally and seem fine but will develope very little power under load. Since I see from one of your photos that you have good access to your distributor, the easiest way to check it's centrifical advance is to remove the distributor cap and see if you can rotate the rotor slightly in a clockwise direction (approx. 3/8 inch at the tip). It should spring back to it's 0 degree position after this test. If your fuel and ignition tests all check out okay it might be worth doing a "power tuning session" where one person rotates the distributor while the helmsman checks for maximum speed.
If you don't already have one it might be a good time to buy Moyer's service and overhaul manual.
