Are you pumping the primer bulb until firm befoer trying to start it?
I'm assuming. When I asked about the bulb, he said, yeah, yeah, I did all that.
So your not working on this yourself then, the engine is not in front of you correct?
Right. This guy's an old salt though and he is basically be-flumoxed. Engine has not run for awhile, but everything looks clean.
This web site needs some better programmers. You get bounced around all over creation when replying.
Whats the engine doing, not starting?
How are you determining that the engine is getting no gas? What exactly do you mean by that?
He took out the plugs and they smell clean.
Was a compression test done on the engine yet?
Right, the engine is not starting.
When was the last time it started? And what has changed between then and now?
He just bought this boat and motor. I will ask about compression check via text. Thanks.
Let me know what he says.
he said that he put his finger in the hole where the spark plug goes and it blew it right off, so he figures it has compression.
Is the saftey lanyard in place? The kill switch clip?
He says it is and that he got a spark.
Well it takes 3 things for the engine to run. Compression, spark and fuel.
You state you have compression.
You say you have spark.
So that means your missing fuel. You also said the carbs were clean, but they are obviously not as clean as you think they are. If you had clean carbs then you would have fuel, and the engine would run.
It really sounds to me like those carbs are boogered up. And need to come off for a proper cleaning/rebuild.

Carbs, being plural, makes me wonder how many carbureators are there on this model? Are there two because it's a two stroke?
There are 2 carbs on the engine because it is a 2 cylinder engine. 1 carb per cylinder.
