Re: New Honda 2.3 outboard not running
On the 2hp Honda it is recommended that you run the carb dry, not that you run the whole fuel tank dry.
That is why there is a fuel on/off lever on the starboard side of the engine (at least on my older BF2A). I always do this when I'm not going to be using the motor for a couple of days. It takes a few minutes at idle speed due to the engine's extreme fuel economy. I guess if you were really impatient you could use the carb drain screw, collect the fuel, then dump it back into the tank.
The carb is so small that it is possible for fuel to evaporate and leave behind varnish in a couple of weeks.
I don't think that any other brand of engine will be any better in this respect. They all use small carbs and fuel varnishing is a problem.
