My neighbors kicked a Toro GTS 21 inch mower with rear bagger to the curb yesterday afternoon.
Of course I had to rescue it and try to get it running again.
I haven't had much time to mess with it ,but I do know it is getting gas and spark.
When the throttle is put in the slow speed position the mower will run for a couple of seconds then die.
A dirty carburetor maybe?
I looked but could not find a model number for the mower .
It isn't under the handle like my Lawnboy.
Would anyone know where Toro liked to put the model numbers on this era of mower?
Thanks in advance

Check the lower edge of the deck, at the rear. Make sure the gas is fresh and the tank/carb isn't contaminated with water. A good carb cleaning may be in order otherwise.

You might get lucky by starting with the small brass screw looking thing on the top of the carb. Its a pilot jet and by removing it and cleaning it you may get lucky with just that alone. Otherwise looks like a complete carb cleaning should do.

Nice machine....should be the Suzuki four cycle on that one.

I can see why it didn't start...the carburetor bowl was filled with water, old gas, and RUST!. i spent a good part of a hot afternoon dissembling, cleaning and trying to remove the rust from everything I could on the carburetor. Carefully reassembled it ,put it back on the mower and tried to start the mower again.
Same thing as before. At best it will run for a bit at low speed then quit.
Darn!
So I called it an afternoon for today.
Does anyone know what the correct NGK plug is for this engine?

um, if its a shorty plug, it might be a c5s,
take the old 1 to o`reilly or whatever is close there, they can cross match it rather quickly

Make sure you're getting unrestricted fuel flow to the carb. There may be a plugged filter, clogged tank vent, or the fuel hose may have disintegrated internally and closed off.
Pull the hose off the carb and drain it into a container. You should get a continuous full flow.
The fuel tank may have crud in it that's blocking the fuel exit.

well it took a second time of removing and cleaning the carburetor ,but It is now running.
Very nice sounding/running engine . Too bad the mower was obviously abused by previous owner(s). Quarter sized hole in the top of the deck,and a chunk broken away on one side. Should have posted a before picture ,but I do believe that that is the most beat up blade I have EVER seen.
They must have been mowing a gravel pit with this mower. When I finally got it running this morning I gave it a trial run across the lawn.
I didn't know it had an engagement for the blade.
It cut grass for about six feet then the blade stopped turning .
Tore it apart and found the belt had torn .
$6.50 and a trip to the local Ace Hardware for a new belt and its cutting like a champ.
Mower does makes a high pitched ringing noise until the blade is engaged.
Then it is nice and quiet.
Definitely a different feeling mower than my Lawnboys.
