List of most all engines for the Ultralite & LSA class of aircraft

Interesting list Ralph.

Like KitPlanes annual engine listing:  it needs to be pared down to those companies that .

1.    Are still in business

2.    Have an engine available for purchase

3.    Have more than 10 in the field actually powering aircraft

4.    More than likely be in business in 2 years. 

Jim, point taken:

However, I was interested in seeing if any advance in small 4 cycle engines around 75-80 lbs. 

My experience with 2 cycle engines on weed eaters, lawn mowers, motorcycles,  chain saws, etc, is enough for me never to fly behind a 2 cycle engine.

To each his own
