G'Day Rule No.1 when diognosing any loss of power. Check compressions. When you have done that get back and I'll give you rule No.2

Re: 70 hp Johnson has no power

Compression OK is what? Values?<br /><br />Verify spark to each cylinder by pulling plug wires off one at a time while running at idle. No RPM change means likely that cylinder has no spark. Check that cylinder with a neon tester in line with the plug wiring. If all have spark, you then need to check fuel below.<br /><br />Next, you need to verify fuel to each cylinder. Take a spay bottle w/ premix and spray into each carb when running at max power. From what you described about the plugs, the top cylinder may not be getting fuel. If the spray routine results in an immediate power improvement, I would suggest rebuilding/clean that carb.
