Re: seahorse 4hp not idleing

It is not getting enough fuel at a rate that will sustain running.
Has the engine been sitting long? Did it ever run for you? Doesn't sound like it will take much to get it running well.
Without knowing more history, it sounds like the carburetor needs a good cleaning.
Don't forget to take a look at the water pump impeller.

I would also check over the ignition system too. A bad coil or dirty points will also have these symptoms.

Ah, yes. With an unknown pedigree there is more to go over.
Fuel, spark, compression; check 'em all to be sure of what you have.
Another key piece of information required will be model number. This can be found on a plate attached to the transom bracket and on an aluminum welch plug pressed in to the top of the engine block.
Good luck.
