Haruko and I are 3/4 of our way on our first long cross country trip in N73HR--made it from Central Texas to Farmington New Mexico in three hops, obtaining 91 Octane unleaded from gas stations close to the airports. After adding 8 gallons here in Farmington, we had some engine problems--no problems at 4000 RPM runup, but at full throttle on takeoff, some incredibly rough running.
What is the collective wisdom of the VAF crew on this? Would bad/over-rated Mogas cause such grief? In the great state of texas, we ran on 93 Octane, and had 91 octane in our first two fill-up along the way, but now this rough stuff.
Staying the night in Farmington, hoping to resolve this tomorrow morning, so any ideas would be appreciated. My first default solution is to drain the gas out and run with 100LL whenever I'm really out and about.
