Re: 40hp Johnson 1963 Carb Question

[twsnagel]

OK. Got the carb kit installed tonight but it’s not running correctly.

I can only get it to start with the choke OFF, which is really odd. And then, it runs really rough.

I’m trying to think what would be wrong – perhaps the float is stuck open in the carb? If it only starts unchoked, then it might seem to be getting too much fuel, if opening the choke and throttle is the only way to get it going.

Is there anything I should check before I pull the entire carb off AGAIN? I need to remove the starter, etc to get it off so I’d prefer not to if there are other things to check first.

As a side note, I have long since disconnected the remote control and am adjusting the throttle on the powerhead. It seems "spongy" and won’t swing past "start" if it’s not in gear. When it is in gear, I can advance the throttle to "fast" but then it springs back to "start". Is this correct behaviour? I know there are a bunch of spark advance / fuel saver things in this engine.

Thanks everyone for your help.
