I had a little time to tinker today and discovered a tank full of varnish. (I had suspected that). I also found that my choke does not work. Can someone explain to me how the choke is supposed to be activated? I suspect electrical problems. Despite those small issues I was able to get her to crank for about 20 seconds before my bucket and hose couldn't keep up. I could not get her to crank again.

The automatic electric choke works on a switched 12v circuit and has a spring mechanism housed in a plastic cover located on the side of the carburetor. These chokes are electrically heated to promote expansion and contraction. When the engine is cold the spring contracts, coiling more tightly. This contraction pulls on the choke rod and puts pressure on the choke to close completely. When the engine is started, the closed choke creates more vacuum in the engine, pulling in more fuel. As soon as the engine starts, a vacuum is applied to the vacuum choke pull-down servo, which in turn pulls the choke open slightly--just enough to allow enough air into the engine to keep it running. As the engine continues to warm up, the electrical choke responds to the heater inside and begins to expand and as it does, it begins to push the choke open.

Ahh, very helpful! Is this vaccuum internal or is there an external vac connection to the choke I am missing?

Internal port on the carburetor.

Thanks! This helps a ton. At least I have a base line for troubleshooting it now.

I spent a few hours tinkering today and made some more progress. I got the engine started and running several times for 30 sec to a minute at a time. That damn water pump will suck a 5 gal bucket dry in a hurry even with a garden hose trying to keep up. How anyone expects the plunger style fake a lake to keep up I have no idea. I think my choke and idle adjustments need some tweaking. I also went through just about every electrical contact on the motor and cleaned them. Some were in terrible condition like these.

I also pumped out 11 gal. of varnished and water laden fuel. The tank came out and got a good scrubbing and hose out. There was some pretty disturbing filth in the fuel tank.

I pulled off the throttle leaver and discovered like several before me the snapped spring that leads to a mon existent neutral lock. I hope I can find a suitable replacement at Lowes, HD, or ACE.
I also got a new horn and horn button to replace the defunct set.

Tomorrow I hope to get the carpet out and tweak the carb. I would love to have this thing running smoothly before I put much more effort into the rest of the boat. I am still not quite sure why it seems to be so ornery. I also noticed it does not seem to be too willing to start immediately after it has been shut off. This is where I wish I had more experience with carb motors. I am not too sure how to determine whether it is running rich or lean. I still have not done my compression test either. I will make a point to do that tomorrow.
