I inherited a Scott Bonnar 45 17" from the previous owner of my home, a lovely man who has since passed away, back in 2007. I used it a few times and it ran well. After a while I reverted back to my rotary mower as the Scott Bonnar took a while to start. Maybe its the spark plug? What do they use? Not sure. Maybe lacks compression also. I'm thinking of restoring it as a project as they do cut a beautiful lawn. Would I be better off restoring the original motor or buying a new one I've seen on websites for approx.$275. What do you think guys will it be worth the effort or maybe spare parts? Anyway hope you're all surviving the Corona virus. Take care. Cheers Greg
