Powermore is MTD's brand. Cub Cadet is just an MTD in "babychit yellow" can buy the same exact thing in your local hardware or Wal-Mart store for less.
Hard starting can be caused by too much valve clearance which would be more common for these OHV engines.
Won't be a backfire in that case.
Also Hard starting can be caused by a burned exhaust valve, there won't be a backfire then either. Backfire in the exhaust is caused by *unburned fuel* that burns off in the muffler. It could be running fine and still have a burned exhaust valve, or excessive valve clearance.
Leakdown test would find exhaust valve leak, but won't tell anything about valve clearance, and these OHV's , checking valve clearance is a *maintenance item*
