Question about Toro Lawn Mower With Toro Power Tools

1 Answer

I prime my tecumseh engine three times as stated. The lawn mower still will not start. How do I investigate to figure out what is wrong? I have taken it to a repair man twice. After I get it back it will start the first couple of times that I try it. Then it goes back to its history of not starting when I prime it 3 times. Sometimes I can prime it 7-9 times and it might start. Sometimes if I prime it 30-40 times it might start the next day.

This sounds like a fuel delivery problem. Maybe remove the carb and tear it down and then soak it overnight in a cleaner after removing all the moving parts...not real hard normally...then let dry and reassemble...If this doesn't improve the fuel delivery problem, maybe get another carb for it....Make sure the air filter is not plugged up, blocking air flow to the carb itself..just something to make sure of at first.

Mower starts when primed but stops when the primed fuel is used up


The jet in the Carb is gummed up. Take that 1/2" bolt off the bottom of the Bowl..That IS the Jet. Many times the Bowl will just hold in place with the Bolt out.. make sure the three holes are clear. 2 are close to the head of this bolt and you should have a real small hole where the threads end. Screw it back in...see what happens

Tecumseh pull start engine on Craftsman Lawn Vac will not pull. Feels like engine is locked up.


the engine is probably not locked ! remove the plug wire, tip up and see if the blade turns. if so, try the rope again. if it wont pull, take top off mower off to investigate the pull rope problem. good-day !

Toro recycler 20017 is very hard to start. it has to be primed many times. after it run a while it starts on one pull.


The carburetor may need to be serviced. You need to find a parts shop that handles Tecumseh parts. You will most likely need a rebuild kit for the carburetor. The carburetor part number is 640303. The rebuild kit is 632809. The Tecumseh engine company shut its' doors 3 years ago. Finding parts is becoming harder and harder. I've heard that someone has bought Tecumseh over the winter but it is unknown when the new parts will hit the market. Best of luck to you.

I have fuel and a good spark, but will not start with out spraying starter fluid into carb.


sounds like your carburetor is plugged, or has lost its prime. As I need to know more, please state the brand of engine it has; briggs or tecumseh, and if briggs, is it a quantum (5 hp or greater with carb not attached to gas tank) or regular?(has the carburetor on top of the gas tank.)

I have same mower and just fixed what seems like a similar problem description. I had gone down the fuel system route and the symptoms just didn't add up. Stopped abruptly w/o sputtering once I reached warm-up temp. Replaced the solid state ignition (34443C now part number 3444D). Problem corrected and just mowed my 1/3rd acre w/ no issues.

I would push the prime button 3 or 4 times it starts then quiet


I took my carburetor off and blew it out with compressed air. Runs great now. Make sure to get all of it. Little screw on bottom has a hole in it too!
