Sorry i dont know where to put this, but does anyone know how to extract more power out of a walk-behind lawnmower? I was cutting some tall grass today and the thing stalled out 8 times after finishing about 1/10th of the lawn so i just gave up. Its a Toro 6hp lawnmower(Briggs and Stratton engine) with RWD . I'm about to buy a new filter and plug for it tomorrow, but just wondering can i put a new carburetor on it? Also a few years ago i saw a "OHV Conversion" kit, does any know who would sell something like this? Also, will nitrous hurt it? Thanks.
