Why won't my Cub Cadet LT1045 start?

I have a Cub Cadet LT1045. Wife ran it out of gas and left out in rain. Tried to start- ran like it had water in gas. Put Drygas in and sprayed wires. Still ran same way. Now it won't start at all. Turns and when fully choke stops due to so much compression. Check the module and it is ok and have full spark. Check the carburator and that is ok- not clogged and float moves freely. All wires hook-up. At a loss.
