NEW for 2014: 1650 Series™ is rated 3.3333 out of 5 by 3.
Rated 1 out of 5 by from short life I only ran this engine 551.6 hours when the rod broke. I change oil every 40-50 hours because its running under load on a generator. Pretty poor service for a "heavy duty engine." Plus its VERY noisy

Rated 5 out of 5 by from Easy starting engine,quiet operation with OHV design Have this engine on a generator I have recently purchased. Engine starts easily,has plenty of power,OHV design will certainly have better fuel economy than traditional L-head engines,and offers quieter operation as well. I have not ever had any problems out of any Briggs powered outdoor equipment.

Rated 4 out of 5 by from Good small engine The oil life is a little short when running a generator. Of course that is continuous running which is the hardest.
