I made some more progress last night, but didn't take as many pictures. I got all the tin off. Removed the carb.
It was running OK, but it is filthy. I have a kit so I guess I'll tear it down and clean it up.
I opened the valve cover and the removed the oil pan.
The balance gears are still there.
And so is the ACR spring!
At least down here the ACR is in working order. When I turn the engine the little ACR flap touches the push rod, but does not open it. I'm guessing that the valves need adjustment? I think I'll start a separate thread on that for more help and advice.
I removed the easy balance gear.
Does this stud stay?
I'll go in with a chisel to get the others out next time.
I have some serious cleaning to do. There's a part of me that wants to thoroughly clean every part and repaint it but there's also a part of me that wants to get this thing back together ASAP. If I only had another Cub, then I could take the time and make it nice.
