Another very easy thing to do to ease starting is to hold the gas pedal all the way to the floor when you atart the warm/hot engine. This helps clear teh engine of unburnt fuel just like unloading a flooded sitiation. Granted it isn't a cure but in all reality short of spending a lot of money there is none.
We went through alot of so called cures and fixes and in the end accomplished very little except spend money. The above helps, learn to live with it, we did.
