I’ll check all these things. I should have just left it and just started in spring per usual. I think it just may be too cold and it also has 30W in the crankcase.Your mower likely came with a Deka 51r battery, which is a quality battery. It takes very little resistance at the battery terminals to create a no start condition. If you removed or loosened the terminals when installing your external charger terminals I would recommend you remove, clean and reattach the battery cables.
Other areas of poor connections are the ground straps to frame, and the front surface of the starter itself.
