Wait a minute - Something just caught my eye. Michael wrote:

"Again, the engine is a new Bernie Bergman supposed 2270 cc engine 240 hp. 40 mm carbs. Yesterday it los s a ton of power and ran really rough. Just got it back from it’s 500 mile device (service?) for new rebuilt engine. "

If it was just serviced and the mechanic was poking around in the engine bay, he might have bumped off a spark plug wire and that would make it run rough and lose a lot of power, too. If the plug ends of the wires have "ball ends" that fit into the holes in the fan shroud they tend to fit pretty tight and sometimes they force themselves out by bumping them or just from vibration over time.

Check to see if any plug wire is off and push it back on until you fell it "click" onto the plug.
