With the older Model A's a contributor to overheating was that trusty (?) timing lever. How is the timing with your engine? Does the distributor advance when you rev it?
Just my 2 cents worth...keep the change... Chap

I will search Old Henry's block flushing method and try that.

I pulled the radiator last night and will take it to the shop this morning.

I have also wondered if timing was an issue leading to this problem. How do I know if the dist. is advancing? I'll admit I am very ignorant when it comes to timing and advance.

The reason I have wondered about timing is that at idle, I get a consistent "pop" from the exhaust and it is especially pronounced while shifting between 1st and 2nd when the clutch is pressed and the load is removed from the engine. Could these two things be related?

By the way, you guys are great! Thank you so much for sharing your knowledge!
