Thanks everyone for the replies. I thought the settings I ended up with were pretty good, with a good pickup. There may be a little scope to lean out the bottom a little more and compensate on the main needle, bit not much. What I don't understand though is why it hasn't been kicking back with the factory settings, which has the same bottom needle position and a richer main needle. If being wet was a problem, wouldn't these settings make things worse if anything? Dan767, thanks for the hose pipe suggestion.
