I've timed it on the ball and it runs pretty good. The standard fuel available here is 91 octane. I'm just wondering if there would be any benefit in advancing the timing a bit from standard.
Cheers

You could probably run a few degrees advanced with no trouble. Just advance it a bit at a time until it pings on grades on hot days and back it off a little bit. You will probably need to re-adjust the idle mixture and speed on the carburator after adjusting the timing for smooth idle.
