Hi Keith,
Looked like the weather was a bit challenging at times in Switzerland. I see the electrics didn't like the rain too much

.
It appears the Swiss put on a great world champs and the new live scoring system was great. Made it exciting, as we at home new the scores before the pilot landed.
Did you get the surging problem sorted and if so, what was the fix? I fitted a new pump, but still the same. It definitely seems like a fuel problem, so i'll richen the reg 1/2 a turn next time out and see what that does.
