The push rod tubes were clean inside. The induction tubes all had some rust inside, two being rusted out. The engine was complete and unmolested; suffering mainly from neglect (internal condensation) and the above mentioned problems. Interestingly, I had two Sextons to chose from when I bought this. For the most part identical. The other one ran. Amazingly, they put a 12 foot bar on the drive shaft and broke the engine loose. With the carb off, and spraying starting fluid into the elbow, they got it to fire. After the carb was re-installed, they drove it all over the farm with no air cleaner before selling it. He wanted more money for it since it was "restored". It is in a museum in southern Indiana now. This a picture of it in it's restored condition. This is how they ran the engine. Jesse.
