What is fuel/oil mixture to operate a Lawnboy lawn mower
It should say on it somewhere. 50 to 1 should be your mixture
SOURCE: my lawn boy 6.5hp mower isblowing fuel out of the muffler
Maybe it's a stuck float valve or a bad float. Had a similar problem on a TORO rider but that turned out to have a pin hole in the brass float, it filled up with gas and let just about the hole tank through the muffler. I changed the brass float and still running to this day! Note: your float may not be brass if it is a newer machine it will be plastic.
SOURCE: lawn mower will not start. I changed spark plug,
If your mower will start when you prime it, and then it dies right away, you have a carberator pluged. If after primeing the mower and it will not even start for a few seconds, you have lost spark. If you have no spark, this can be cause by two things. First, the magnito could have gone back, but this dosen't happen to often, but it can happen. First, check to see that the cable from the brake handle has not stretched. This controls engine brake and its also the kill switch, which kills the spark. Get acess to your engine brake, and you will find a wire connected to a tab. Remove this wire and try to start the mower. If it starts, replace the control cable. If it dosen't start, hook the wire back up and replace the magnito. I hope this is of some help

FOR SURE CHECK ALL PREVIOUSLY MENTIONED ITEMS , TRY THIS...ALMOST GUARANTEE IT WILL RUN............ REMOVE "ALL" OLD FUEL, REFILL WITH FRESH HIGHEST OCTANE FUEL. REPLACE SPARK PLUG (YES, EVEN IF IT LOOKS OK!) GAIN ACCESS TO CARB OPENING, REMOVE AIR FILTER..OR WHATEVER. USING SPRAY CARB CLEANER, FILL ENTIRE CARB AND FLOATBOWL WITH CLEANER....WAIT OVERNIGHT IF POSSIBLE..IT WILL EVAPORATE. NEXT DAY SHOOT MORE INTO CARB..GETTING ANY JETS, ORIFICES ETC..FILL FLOAT BOWL AGAIN. P.S. CLEAN OR REPLACE AIR FILTER IF NEEDED! WAIT A WHILE, GAP NEW SPARK PLUG, INTRODUCE APPROX. 1-2 OZ. OF FRESH GAS INTO PLUG HOLE...QUICKLY RE-INSTALL SPARK PLUG ..WITH ON/OFF SWITCH-BAR OFF..PULL OR CRANK ENGINE A FEW TIMES. MAKE SURE IGNITION CAN FIRE, CRANK(ELECT. START) OR PULL STARTER ROPE & MOWER SHOULD FIRE OVER. IF IT STARTS..RUNS..THEN STALLS (AFTER USING UP GAS IN CARB, TRY IT AGAIN. IF IT CONTINUES TO STALL QUICKLY...YOU WILL NEED AT LEAST A CARBURATOR REBUILD, OR IF NO START AT ALL..YOU NEED TO SEE IF PLUG IS FIRING.
