Re: 40hp Johnson 1963 Carb Question

[twsnagel]

Fuel pump is good.

I tore the carb off again last night, cleaned it again, removed all the core plugs, cleaned it again, reassembled it.

Nothing. It still doesn’t start right.

When I crank it on "choke", liquid fuel builds up behind the choke shutter and then runs out if I open the choke after cranking.

I’ve checked the spark – it’s good and bright from both cylinders. The wires are not reversed.

I will try new plugs tonight just in case something is strange.

I do have a question – Do I have a part missing? This is an RDS-25D and has the fixed high speed jet. When I take the "drain plug" out of the carb bowl, I can see brass in there but there is no screwdriver slot as the manual says there should be.

Is there a need to pull the flywheel and check the points if I’m getting a good strong spark? I don’t have the correct kind of puller so I’ll have to go shopping. What size bolts are in the top of the flywheel?

Other than that, what on earth could be wrong? I’m so close to scrapping this boat.
