I have a 125 mercury 2 stroke outboard, made in 2000. I'm performing a slew of diagnostics. The enricher valve on this engine is electrical. When I push the key in (or press the button on top of the enricher itself) it delivers gas to the cylinders.

To test it I removed the inbound fuel line to the value. Squeezed the primer bulb, and got a good stream of has come out. I then reconnected that line and disconnected the outbound fuel line at the enricher. Then I primed the bulb again and pressed the button on top if the valve a squirt of fuel came out (a tablespoon maybe two). I repeated the same by pressing in the ignition key.

So is a tablespoon or two of fuel indicate the valve is working properly? It doesn't seem like enough fuel to get a cold motor started.

Generally a cold start requires 5 to 8 turns of the key on my engine. Although I will prime the bulb again after a few turns of the key the bulb gets firm in a couple of squeezes, implying the carbs are full.

Thanks.

Measure the fuel coming out of the enricher with the engine cranking and key pushed in..

The enricher tests are shown in 3B-24 of the service manual, 90-830234. If you do not have this manual, see my message to you in Notifications at the top of this page.

Do you have the s/n of your engine?

Thanks. I just did that and the fuel comes out of the value as the engine cranks. I would call it pulsating fuel.

That means the enricher is working I assume?
