I have a White lawn tractor with a 15.5hp OHV engine on it. I am having an issue where the starter cannot turn the engine over past the compression stroke. With the spark plug out, the engine turns over freely, and the valves are moving as they should. If you turn the engine over without the plug, its fine until you plug the hole, and then the starter tries to turn it over, but can't. I have replaced the starter, but no luck. Same issue.
Last year, this tractor ran fine, and all it has done since then is sit in my basement. This year, this problem arose.

Any help? thanks!
