John Deere LA145 Lawn Tractor - won't start
My battery has been on a charger during the winter. It was placed back in the mower over the weekend. According to the tester, it has a full charge. The mower *will* crank and sound like it's going to start any second - but doesn't! It has a full tank of gas, the oil is good, Spark plugs are OK, the fuel line shows it is getting gas, and the fuse is OK.
I made sure the blades were off when I tried to start it.
What else am I missing ??
Thanks for your help !

what engine is it? you might want to do a compression check. if you can keep your finger blocking the spark plug hole while cranking the engine, that is probably a problem. you could have a bad head gasket, bad rings, or incorrect valve lash.
pour a shot of gas into the spark plug hole and try again.
your spark gap should be around .030" that is about a credit card thickness.
