Is this normal?

[55'Fleetwin7.5]

I finally got my 1957 35hp Lark to start after the carb rebuild... Shot a few squirts down the throat and one in each cylinder... after a few seconds... we had ignition! I will tune it further on the water.

QUESTION? when I turned it off by pressing the "off / choke" button, I noticed a few drops of furl coming out by the choke plate. Not a ton but several drops then it stopped. I started it again no problem or primer needed... when I stopped it, same thing a few drops then stopped. Is this normal or does it need some attention.

Thanks,

Tom.

This fuel will end up dripping into my silencer body.

Re: Is this normal?

If you are stopping the engine by choking, fuel dripping out the carb throat would be normal.

Re: Is this normal?

That is great news... My system has a red start button and a black choke /off button. The only way I know how to stop the motor is the "choke" button. If there is another way I don't know it. My throttle all the way down is not enough to make it quit... close but not enough.

Thanks for your help... I think I can put it back together again now.

PS. How do I determine if my float is operating properly? what are the telltales? Thanks

The older Big Twins used the choke to kill the engine. I don't know when they added the kill wires, but it's possible to add them onto your engine if it doesn't have them already...the next time you have the flywheel off, anyhow.

Still, no harm done by using the choke to kill the engine. Best to let it idle down completely, though, to avoid possibly flooding the engine.

Re: Is this normal?

I apologize if I am hijacking this thread, but choke to kill the engine is okay? I have a 68 20 HP Johnson that I got without the kill button, and was told just to choke it to stop it. I was considering rigging up a killswitch (actually a lanyard-style killswitch since I tend to motor alone), but if choking the engine won't do any harm, I'd rather do that than have to take the flywheel and ignition plate off again.

Re: Is this normal?

choking to kill can make it harder to restart. boating alone, you are much better with a kill switch and lanyard. the 2 black wire coming from under the fly wheel, are the kill wire, they just need to go to ground.

Re: Is this normal?

So... I find the black wire that goes from one of the coils and exits under the plate... I then install a kill switch to "ground" that circuit? Is that the idea? I think I can handle it.

Re: Is this normal?

you need to kill both coils, it will run on one. but you've got the idea.

Thanks for that! While I am at it... have anything on synching carbs with magneto... I just replaced ignition / carb etc... want to make sure all is correct before I button everything back up.

Thanks again.
