Hello everyone. New here but not to small engine work. I need a little help and sorry if this has been asked. I couldn't find any info on this subject. I have a Briggs 5550/8550 max generator with a 10hp Briggs engine. I want to swap the engine to a Duramax 16hp or similar 420cc engine. The shaft size is fine but my concern is will the stronger engine affect the power output? I don't want to burn up the generator.
