I tried reseating the carb, I thought you might be on to something there Minn. The clamp was not as tight as I would have liked. But I had the same results.
I have now removed the gas tank, it looked like the fuel line may have had a bit of a kink in it so I shortened the brass tubes just a little. One thing I am concerned about is that there is no way to rap foam around the tank. That is how tight a fit it is. The manual does not tell you to wrap it either. I did not see any foaming or bubbles in the fuel. Should I be concerned with this?
