What is the temperature of each cylinder head at idle? Are there white or black thermostats in the heads?

Have the recirculation valves, fittings, and hoses been checked, cleaned, and tested?

What is the compression of each cylinder?

What is the idle timing?

Has the motor been decarboned within the last 100 hours?

Have the black intake manifold gaskets been replaced with the brown or reddish colored ones?

Are you running Champion QL78YC plugs gapped to .030"?

Have the side covers on the carbs been checked for warping and are the gaskets brown? If they are black, someone did not rebuild your carbs.
