ignition timing

[Tom Wesenberg]

My 29 Tudor had a cheap 2 row radiator when I bought the car. It lost one to two quarts of coolant every 10 miles. It's just too small for the flow.

A leaky head gasket won't show up until you ask the engine to do some work, like up a grade or pushed faster than 35 or so. Block the wheels in high gear and put a strain on the engine while your helper watches in the filler neck for bubbles. There are lots of Model A's "out there" that will put-put around town all day but refuse to do road work due to a leaky head gasket.

Ummm, Me thinks there are probably easier and safer ways to check for combustion gases in your coolant... just sayin'.

let us know how you make out

Timing is confirmed by timing light while running so that is good. Compression has been checked when hot and no sign of combustion gas, oil, etc in coolant. My experience with lost coolant mirrors Tom's where I lose about a quart every 10 miles or so.

"Timing is confirmed by timing light while running"
excellent.
I assume that you mean the timing is zero degrees at idle with the spark lever all the way up.
Super good idea when you are having issues that go beyond normal setup procedures
