Success can be exhausting

No, the Landshark hasn't sold, but it is running the best it has since I bought it. I ran a can of SeaFoam through the engine and exorcised 25 years of buildup. I may try it again in a few weeks to see if there is further improvement. After the SeaFoam, I had to reset the timing and the idle. Unless it broke my fuel gauge, I think I'll be getting slightly more than the six miles per gallon the Landshark was posting previously. 

update, so, the mileage has increased to a whopping 10 City, 14 Highway. Still not great. It's obviously running rich from the exhaust smell, but I think I'll run a few weeks like this, SeaFoam it again, and then start fooling with the mixture. So far no further interest from buyers, but as Spring gets closer, the idea of a project car becomes more appealing.
