1974 Chrysler 45hp. Motor seems to be in tip top shape. New plugs, new fuel lines, fuel pump diaphragm in good shape, did the timing, points, water pump, and thermostat. It starts and runs great.
It's attached at a 1969 Chrysler Cadet which is about 14" and weighs 300-400lbs. I have maybe another 100lbs of gear in there.
I had it out on the lake over the course of a few days and it was absolutely destroying fuel. I'd burn about 3 gallons in 20 minutes. WOT or cruising range didn't seem to matter. It's doing about 4950 rpm at WOT with a 12 1/2 pitch prop.
Here's the weird part. On the last day on the water it lost it's appetite for dinosaur goo and burned only 1/8th of a tank on the same 20 minute run to town. I hadn't changed anything. Weather was about the same as it was the other days.
My thoughts are that the needle valve is letting gas through but could that explain such a massive fuel consumption? I skipped replacing the needle when I overhauled the carbs because it looked like it was in good shape.
