Question about Toro Power Lawn Mower

1 Answer

I have a Toro 6.75 walk behind mower. Upon changing oil, I overfilled it, and ran it a couple times before realizing it. Now, it starts fine, runs great for a while, till it gets good and warmed up. Oil leaks from what apears to be some sort of throttle linkage on the left rear side of the case. It also blows oil into air cleaner. When its still cool, it runs like a champ, once its warm, it seems to lose most of its throttle and torque. makes cutting even the shortest grass seem like cutting through thich, tall, wet grass. It has new plug, fresh oil(at proper capacity), and air breather. is there some sort of o-ring gasket i could have blown that controls throttle response?

Toro personal pace 20372, starts fine, runs well for 30 or 40 minutes then dies. Starts up again when cooled down just a bit.


Need fuel that is not more than a couple months old

Need a good or clean spark plug

Have no idea how old it is, or how many years
you have used it

Sometimes you have to remove the head & clean the
carbon off the piston & head
That is a tune-up on small equipment

Make sure the air filter is clean

They usually start with the air filter off,but you don't
want to do that all the time

Oil mixture for 1985f series 2 cycle lawn-boy mower


Contact your dealer ! but 32:1 sounds correct. 8 ounces of Lawnboy oil to two gallons of gasoline ....is 32:1, 8 ounces of oil to one gallon of fuel is 16:1 for the real old lawnboys,
When Toro bought out OMC,and started using Tecumseh mowers,the ratio changed in the late 80's or early nineties ! IIRC :o)

Have a self-starting, self propelled toro lawn mower about 5 years old, I ran it out of gas by accident & now it won't start


It seems to be an obstruction in your fuel delivery system. Get a can of ether and a spray a short burst of it into the breather area near the carburetor, if the mower starts up and then stalls out, then you may need to get your carburetor serviced.

Toro 5/24 snowblower will start but dies when i start throwing snow


Had the same problem with my toro blower 5/24 and small engine guy told me that there is a screw underneath the carburator adjust it out (left) about a quarter of turn. I did that and the blower ran good for awhile but it is starting to run rough again so I think I will take it in and have it tuned up. It sounds to me like a fuel delivery problem, could be some gunk in the carberator. TW

Toro Electric Start Problem


Remove spark plug and observe condition. Fouled with oil, bad motor. With plug removed pull rope several times to blow out cylinder. Spray WD40 in spark plug hole, pull rope several times see if oil blows out. Spray a lot of starter fluid in spark plug hole, replace plug. Spray starter fluid in air cleaner area of carb, try to start. Replace spark plug, try to start. Ensure oil is full, all mowers have a low oil sensor now. 30w oil. Always use Stabile in gas.

HELP, 2007 Toro walk behind mower


There is a drain plug on the block of the motor usually it looks square. if its not behind the blade on the under carriage, then it will be on top above the blades were the motor is visible. you may have to tip the mower on its side to completely drain all the oil. but the plug is always going to be on the motor either on the side or on the bottom. if the plug is on the bottom were the blade is remove the spark plug wire first. a mower can start if you turn the blade by hand and that would be vary bad news so always take the spark plug wire off and make sure it can not come in contact with the spark plug before going underneath the mower.

Billows of white smoke when Toro lawn mower runs


You overfilled the oil. If the mower runs, just go ahead and mow grass until it runs the oil out of the gas tank. Or you can empty the gas tank and fill with new gas. White smoke is not a serious problem. Only a hassle.

Won't start


the blades may be locked. remove the spark plug cap so the mower won't start unexpectedly. tilt the mower on its side, air filter facing upwards. work the blades until they loosen and turn freely.
