Compression

If it was "warmed up", it ran: but with 45 psi I dont see how it even lit off. Put some ATF in the cylinders, like a few squirts from an oil can in each spark plug and let it sit overnight or as long as you can, that seems to loosen stuck rings pretty good. Do a compression test with the plugs out and coil wire pulled. Screw it in, bump 3 revolutions or until the pressure stops going up. note and repeat on next cylinder.
