New member here-- great site.
Briggs and stratton says maximum operating angle for engine is 15 degrees.
but i need to operate a 5 hp horizontal shaft at 20 degrees for a special application.

Can i add extra oil to crankcase to compensate for angle?

To expand on L-t-C's post;
Is the 15 deg limit due to oil starvation,
safety (mower tipping over),
or proper float function?

Or any combination of the above?:confused:
