Default Hard starting 4-stroke outboard

I wondered if tipping the motor up at the ramp might be a factor,
but that's rarely necessary at the ramp I use the most.


So, are you tipping the motor up? Like, maybe every third trip?

Best answer gets 15 virtual beers.


Have you already established the problem and are testing the group?

My suggestion is to run the gas out of the motor before putting the boat
away. There are two things that leaving the gas in the carburetor could be
contributing to:

1) Sitting for a week or two the gas will start to evaporate. As it
evaporates the "stuff" remaining gets condensed into something that is not
exactly what the motor likes to run on. Those million pulls might be
purging the gunk out of the bottom.

2) Tipping the engine up might allow gas to flow into the intake manifold,
flooding the engine.


I have a 9.9 Hp two stroke. When I run the fuel out of the carburetor it
will start on the first pull the next time, no matter how long the time
period was (after I squeeze the bulb and pump the gas up). If I don't drain
the gas out it will take a half dozen pulls to get it to start. Not as bad
as yours, certainly, but perhaps the cause is the same.
