How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Pour penetrating oil into the cable (Photo 1). Grab the inner cable with pliers and work it up and down to loosen it. When the cable moves freely and all the penetrating oil has drained out, squirt silicone lubricant into the funnel to keep the cable sliding freely. Reinstall the cable (Photo 2).
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
Governor springs hold the throttle in the desired maximum speed.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.

Mower runs at slow speed only
ANSWER : Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.If the mower is over a couple years old, then I also recommend that youbuy and install a new carburetor repair kit, because the diaphragm willget hard and that will cause it to be hard to crank.When you clean your carburetor and remove the jet screws, count the number of turns it takes to seat the jets from their original position.That way when you go to put the jets back in, you know how many turnsthey were in/out.Please rate me, ThanksGood Luck, I hope this helped

Lawn mower will start and run for 5 seconds and shut down
ANSWER : Will it stay running with your choke on? if so then clean your carb. if not then look for a blockage from tank to carb. ie fuel shut off, deteriorated fuel line. plugged filter etc

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!

Carb problems wont stay running unless i unplug and plug in the anti diesel switch the plug on the fuel bowl
ANSWER : Check and see if all your carb jets or clean sound like some dirt got into one

I have a Poulan push mower that after mowing in a ditch started making a loud noise and running rough. It almost sounded as if metal was hitting metal. The mower was vibrating more than normal. I checked under the mower and nothing is hitting. After a few times of stopping the mower engine because it sound as if it is going to die down the mower will not start now. The shaft does not appear bent and the blade appears ok. The mower has oil, a good spark plug and a clean air filter. It was running fine until that moment. I did not see anything that I hit but it is possible I hit something in the ditch like a pine cone or branch. What could the problem be and how would I go about fixing it?
ANSWER : If you are sure the oil level is correct then it sounds like it’s about to die, unfortunately. A pine cone shouldn’t cause any damage, but a large branch may do so. Was it smoking before you shut it down? The vibration could be caused from a bent blade. It could also be caused from a part breaking in the motor. I wish I could have given you better news!

Good Luck,

Jim

I have a toro multicycler 650series power mower and it is like the choke is jammed on. running very rich, throttle not picking up properly, throwing out volumes of black fumes and cutting out. How do I adjust the fuel mix?
ANSWER : Replace the needle valve and seat check the float for fluid inside clean the jets

Mower start up and runs, but starts to cut back, and smokes just a little bit. The mower stops smoking when it throttle up. It will continue to run but not at full throttle. I can hold a finger gently over the fuel primer bulb and it will throttle up for a small time.
ANSWER : It sounds like she’s being deprived of the correct fuel / air mixture due to a dirty carburetor (the biggest problem with mowers when gas is left to sit for a period of time). If you do not know how to take the carburetor apart and clean it thoroughly, then I suggest taking it to the local shop (hardware store or mower shop) and having it tuned up. It’ll probably be just fine and worth the money. Hope this helps and good luck.James
