I was running my TO20 the other day to burn a little old gas out. IT started right away and was running fine. When it quit running I put fresh gas in and it did not want to start, acted like it wanted to back fire. It did start but was running rough for a while then cleared out. I thought something might have been blocking the fuel flow and it cleared itself out.
I went to start it the next day and I had the same problems starting. I pulled the valve cover and took off the rocker arm and noticed several bent push rods. The rocker arm had been plugged in two of the center oiling ports.
I pulled the head and several valves were almost stuck and had to be tapped out with a hammer. They looked like the oil had been baked on them when looking at them from piston side.
Question 1. With the oil ports clogged I can understand the heat to bake on the oil but would there be enough oil for it to bake on them?
Question 2. After researching valve kits they all seem to come with pin type connectors. Are they safe and if I get them is there any other parts I should get like end caps, different type of stem guards etc.
Question 3. what about oil seals on the valves, I am not sure mine had them. What do they look like?
