I am anticipating the first tests I plan to do on a non-running, unrestored model T engine. I'll take off inspection plates and look at the transmission, rods and mains. Do a compression test before taking off the head.

Was curious what the average voltage was when hand cranking a single stack (1920s) magneto in "good" condition. And what should I expect to get after removing plugs and giving it a little more speed without any compression.

curious to see what you get for answers on this. I can get mine to start on the mag when warm.

My current T has a 1918 engine with a mag coil I rebuilt around 1980. I never did anything to the magnets ... didn't know how to test them. It still starts cold on mag with the spark advanced about five notches. Takes a sequence of four priming cranks (with switch off) to get gas in the cylinders first.

My 14 is like Mark's. I put in a rebuilt field coil but did nothing to the magnets. It did already have a single stack coil and later magnets but I didn't know anything about charging them. Starts on mag cold after a few pulls choked. It wouldn't do that though until I got the 4 coils rebuilt.

Quite often I will hand crank my '27 on mag from cold. Usually when I park it I will turn off the gas, speed it up a bit and let it run out of gas on mag. When I want to start it again I just turn on the gas and choke it a couple of pulls and about the third or fourth pull it is running

In all the years I've driven my T I have yet to have a set of coils that were checked and adjusted using a HCCT. Am building one this winter. But like I said my T has always started on mag so am looking forward to model T bliss once I have the opportunity to put "properly adjusted" coils in there.
