Just purchased a Toro Rear Engine Rider 8-32 with B/S 8 hp. Runs great but wish it had a little more power. How much additional hp could get I get with maximum overhaul, i.e., bore the cylinder, larger piston, and shaving head. Or ideally I would like to find a 12 hp but not sure if it would fit. Appreciate any info you can provide............

Hi and welcome to TSF

I think I would check into a 10-12HP engine before I would try to soup up an 8 HP. Should not be that hard. Of course you may have to drill new mounting holes, match the electrical up.

Unless you have "free" access to a machine shop and a buddy who can get you the parts at cost, trying to upgrade that engine would cost more than buying a new engine.

5hp briggs and stratton
I have rebuilt the carb on my 5hp b&s lawn mower and now it won't start. I also added new air filter and new spark plug. I checked the carb to make sure that there was fuel in the bowl after the rebuild and there was. What should I try next. Thank You.
