Hey folks. New to the forum. I have a Toro SS 5000 with a Kawasaki FR691v 23 HP engine. Recently, it has started backfiring when I pull the switch to engage the blades. I've heard everything from it possibly being a fuel solenoid to the brake module. Hard to get an answer out of my local dealer or the manufacturer. I currently don't really have a way to get it to a shop so if I could do it myself it would be great. Thoughts? Any help will be greatly appreciated.
 
BAckfires, blows a little smoke, gets louder exhaust for a few seconds then settls down ?
All signs of a blown head gasket.
Run the engine for a few minutes, turn it off then pull the dip stick.
Soke rising confirms a gasket.
 
No indication of a bad gasket. Did the cut off the solenoid tip trick. Seemed to run fin, but started backfiring again. Not as bad as before though.

Your carb has a crankcase vent just above it, when the engine inhales it also draws in crankcase fumes, which can contain trace amounts of oil.

Make sure your oil level is not overfilled.

Where did you get that .002 spec ? Don't want to burn any valves. They should set same as mine between .005 - 007
