bad gas is causing all kinds of problems in small engines..

they are feeding us the WORST gasoline ever..

Up to 20% alcohol means you don't get the mileage you should,

your fuel lines are leaching,

and sitting for a month or 2 leaves residues in the carb that cause the effect you described.

ALWAYS shut-off gravity-fed fuel systems when not running.

Low Oil can give the same effect,

over heating from bad ventillation, or OLD DIRTY oil can do it.

an ignition coil that overheats can do that,

a bad gas-cap on a pressurized system like they require in California. (aren't we blessed.)

..and you're far away from Calif.. it's not that.

I know.. the air filter to soot-up,

and fouled the spark plug.

Usually I'm kinda fast at troubleshooting..

did I get it yet ??

Marco, you said you just changed the fluids, maybe you didn't put enough oil back in it. (Low oil shutdown)

The first time I changed my oil, I was told by the guy at the store it took 1.5 qts. Wrong. There was so much oil in it that it came back up into the carb and soaked the air filter, choking the engine off and ruining a new filter. That's what I get for listening to the guy selling me parts. Ha

Yeah, all Honda engines seem to have this. Once had the machine on a slight incline and it kept shutting off. Drove me batty until I figured out what was going on...

Had the same problem 4 yrs ago. Brand new 13hp Honda. Level ground, faulty low oil alert switch.

There is a wire on the outside of the engine block that can be eaisly disconnected to bypass this sensor. I wouldn't recommend leaving it disconnected. I forgot where it is but it only takes a few seconds to find it.

What kind of fuel pump are you using? I put in a electric one and that fixed the problem.

this year i have been having the same trouble as you. i am thinking it might be the ethanol garbage. a lot of marine engines have been failing and they say it is from that. I started adding the additive this week. I hope it isn't too late. something c-100 it is called ,and adding a couple cap fulls of marvel's mystery oil.

[Jerry 24]

great choice..

both of them..

Marvelous choice for reliability !

those marine engines have been dropoping like flies for the past 3 or 4 years..

..from those "gum deposits" causing stuck valves, and bent push-rods.
