Engine help on this one

[msharp6666]

have a kohler command pro 13 started and loaded on trailer this morning. would not start 1 hour later. changed coil just to be on safe side. still will not start. has fire, fuel, even sprayed starting fluid in carb, no start. sounds like air is blowing back up carb instead of sucking.

Sharp, Keep going over the basics and search troubleshooting in this forum...e.g. compression. Then ask again.
