Thanks for the welcome! I have a ride on 13hp Briggs and stratton be Murray mower built in 1999. It has been running fine but today it suddenly started to cut out when I engage the blades. I've checked that the cutting deck was not clogged, fuel was running freely, and carb was clean. It moves along fine in all gears but just stalls when I engage the blades slowly at any engine speed. The belts look ok, and I can move all the pullys by hand. Is this possibly a fuel mix / carb problem? Seems strange that it just suddenly happened. Engine is not burning oil. At a loss!! Any advice welcome cheers
