My A4 is particularly susceptible to water in the fuel tank. I had a bear of a time getting the baby up and running even when there was miniscule amounts of water getting in the carb. It would start and idle, but as I would leave the harbor it would soon die, then start at random and continue to run again. Prob solved when i switched to a remote 6 gallon outboard style tank with fresh fuel. Maybe check the fuel bowl just before the carb and pour into a glass jar to make sure no water in fuel... then maybe a racor or other fuel water separator? Best of luck. These engines are simple but boy do they seem to have alot of gremlins. Start with the simple stuff ;o)
