Not to add insult to injury

, but I put a plastic uniflow on my Pathfinder with an O.S. .40FP. You can see inside the tank so I know the uniflow was not plugged. This was NOT on pressure, but vented. The engine would not run properly. Open the overflow and cap the uniflow and guess what? A perfect stunt run. That happens sometimes. I later received the .46LA, switched to the open uniflow and capped overflow and...a perfect stunt run, after break-in, of course. That happens.
I had a guy in the middle of the circle once. I got flustered and tried to do an outside at 20 feet

. Came in last that NATS.
