Re: Use of avgas?
On a long tour a couple of years ago, I had trouble with the engine pinging. One of the first things I did after checking the timing was to run a tank or two of higher octane fuel. I tried 98 octane whereas the ordinary stuff I use is 91. It made no difference whatsoever, even after I found and rectified the problem.
I bet I know what you're thinking right now - so what was the problem?
It was the Model A #3/4 crossfire. I fitted the new distributor body I carry and all was back to normal.
