Not quite sure. It's back at the painters now and he couldn't explain what happened. First gas in was ethanol laced. I discovered this before I mixed the race gas the day of the Spokane shorttrack. It ran OK, but in the main, the fuel filter became almost completely plugged. The motor wanted to die, but made it to the end.
The next morning I attempted to drain the tank and found there was a stack of crap in the filter and minimal fuel flow.
