Brent,

I'm close to you, Colorado Springs area (6,700'). 2332 engine & I run a electric 'pusher' pump located in the front, below the tank. An advantage is it raises the fuel line pressure, as opposed to the mechanical 'sucker' pump. Raising the pressure increases the boiling temp. It also creates a separation between the hot engine case & the fuel line. Mechanical pumps directly connect the case to the fuel line, increasing heat soak potential. I agree & run non-oxygenated fuel.

All that rambling being said, I would 1st try changing your oil to lower viscosity. Frozen molasses creates heat.
