I borrowed a friend's Toro mower to mow the VERY high and damp grass in the back yard. I have never used a mower this nice and powerful (6.5 B&S). Nor have i ever used a mower with a bag attachment. I was happy to have the bag attachment since it would eliminate the need to rake after mowing. The mower worked fine and even cut through the heavy grass that had gone to seed. I kept pressing on the bag to check for fullness but it seemed to be OK. I was almost ready to stop when the mow ceased to work. I cleaned out the bag which was only about half full. However, the underside WAS very full of wet grass. I cleaned that part out and then left the engine to cool off while I went for a cool drink. After 20 minutes, I went to restart the engine but could not even get it to turn over. Before I started for the first time, I removed the old sparkplug (Champion RJ19LM) and saw that it was fouled. So, I replaced the plug with a brand new plug that I had recently purchased for my old mower. The new plug is a J19LM. Could this sparkplug be the problem? I went to an independent auto parts store to get the original RJ19LM, but he gave me the J19LM instead. I asked what the "R" meant and he said "Resistor." He said that the J19LM should work just as well. So, is it the sparkplug or something else? Thanking you in advance for any advice!!!
You probably just flooded your engine. With the spk plg out, let the excess fuel evaporate and dry out. When you cut grass that is "wet" and even long, it is typical for the chute to clog up because the wetness is heavy and the clippings stick together. Use a slower ground speed to allow the clippings to get as far as the bag before clogging at the chute.
