PIREP - Yankee

I had dual impulse couplings, and my left mag failed, so I put mine on the

left side. I connected the manifold pressure line to take advantage of the

timing advance. I would agree with everything that has been reported, easier

starts, smoother running, lower fuel consumption, and actually runs reasonably

smoothly lean of peak, lowering fuel burn even more.

This is an O320 in an AA1-C. I powered back to about 105 KIAS, leaned

aggressively and got down to 3.7 GPH, which yields substantially better MPG

than the stock O235. Of course, that was just out of curiosity, I burn the gas

and pass Tigers in the real world.
