This past weekend I started by setting up a temporary fuel pump to drain the old gas from both tanks. The port tank was nearly empty, while the starboard tank had roughly 20 gallons, so I ended up draining about 25 gallons in total. The gas was obviously very old but there was not a lot of sediment in it (although I was running a small filter before the pump) which I see as a good sign. With this cheap fuel pump hooked up to a new battery I was able to drain the tanks to dry in less than 2 hours. Next, I cleaned up the manifolds and risers, painted them while I had them off, and reinstalled the manifolds with new gaskets. I also drained the oil, although I still have to change the filter and refill it with fresh oil. I am looking forward to next weekend, as I will be finishing reassembly with the risers and new spark plugs. I also have to install the new belt and water impeller. Does anyone know the proper way to reinstall the belt on one of these? I can't find a lot of information on the appropriate procedure for this engine, and I'm not sure how to adjust the tension to slip it on and retighten it. After that I hope to crank the ignition and see what I get. Will be interesting to see how everything is working in terms of spark and the TBI. My main worry right now is that the TBI system will have fried electronics, but I have no indication to believe that is true- as even the trailer lights, exposed to the elements all this time, still work. Kind of a short update, but she's coming along nicely, very excited to slip that key in and see what happens.
