Deferring to you with more exposure to repairs and parts...It's hard for me to imagine finding a good engine where other major components have failed. At least with respect to Briggs. Seems like I see more decks for sale than used engines. A while back on this thread there was interesting discussion about the application of H-Frt Chinese sourced AC engines (YES, I know, if I think I had problems with Intek then just wait) . The writer had mentioned the crazy warranty available with H-Frt so that every couple years he could keep getting new ones for (virtually) nothing once the warranty was in place. Do not know about fit, form and coupling problems. Just saying....:laughing:
