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 :

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.
The mower surges when the carburetor sucks air through an unsealed gap in the air intake manifold instead of through the air filter. Dirty carburetor. Clogged fuel jets inside the carburetor commonly cause the lawn mower engine to surge. Clogged jets can`t provide the right mix of air and fuel to the engine.
A wide variety of issues can prompt an engine surge. The problem may involve an annoying change (up/down) of engine speed while cruising at a steady pace, a low drop (or even cut-out) at idle or when approaching a stop, a wild high engine speed of several thousand rpm followed by a drop to near zero, etc.
Again, keeping all else constant, more duration will make the engine less efficient at low rpm, with more overlap dilution of the induction charge, and the later intake valve closing reducing the trapping efficiency. Therefore, a long-duration cam will cause rough running at idle (lope) and a loss of low-rpm torque.
This usually happens because the engine has high mileage, or a particular failure, like overheating, caused the gasket to blow. To check for a leaking head gasket, do a cylinder compression test using a vacuum gauge. Consult your vehicle repair manual for this. Inspect the intake manifold gasket for leaks.
It can be caused by various factors, fuel injection problems, bad spark plugs, a malfunctioning air sensor, might be a dirty air filter, and troubles with the engine control. Other issues of the fuel ignition system can also trigger surging when stopped.
A bad spark plug could also cause misfiring, surging, or hesitating. Engine misfiring could be caused by a damaged spark plug tip. Engine surging or hesitating could be from the over intake of air into the engine, indicating a potential spark plug issue.
Surging and Lagging

Another good indication that your spark plugs are dirty or worn is if your vehicle experiences surges of speed, resulting in a jerking acceleration. These surges occur because your spark plugs are not igniting the fuel in your engine at the proper rate, resulting in an uneven speed.

Hesitating cars and bucking cars often have worn out fuel filters, fuel pumps, oxygen sensors, EGR valves, spark plugs, or air filters.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
There are several reasons that surging occurs. A restriction to flow or fouling in the air/gas system is one possible factor. This could be caused by a dirty charge air cooler, or dirt or contamination on a nozzle ring, for example.
the lope comes from what is effectively(in engine combustion terms) an overlap between one cylinder opening and another closing. These cams are designed to maximize the engine combustion cycle at very high RPMS with VERY large and Very Dense fuel air mixtures.
Basically, these are profiles with a very long exhaust duration. They also are ground with tight lobe separation and with 5° of advance. This creates lots of overlap, resulting in a loss of vacuum and a lumpy idle.

You can either clean the air filters, or you can replace them with new ones. If you have a foam filter, you can clean it with a drop of dish soap and warm water. Remember to air-dry them before using them again. But if you have paper air filters, you must replace them during the maintenance of your mower.
Why does hunting happen? The most common cause for engine hunting is a blockage in the carburettor. Put simply, this restricts the fuel flow in the carburettor causing the engine to slow down. To try to compensate for this, the engine`s governor opens the throttle to allow more fuel into the engine.

I have a mt2000-h magnum pump, but did not get the controlls with the pump. Im trying to figure out how to get the two speeds out of the motor when i only have one set of motor leads for the 220v hook up. motor data tag says 1750-3425 for motor rpm. how does this motor produce two differant rpm’s without two differant sets of windings?
ANSWER : You have two windings if it is two speed. What you need is a switch
before your wires come into the motor you need to take one of the leads and run it through a high low switch. This will simply take one of your 110v lines and make it go to high and low speed on the motor.
Green will go to ground, one 110v line will go to common and the other goes to the switch. It comes out as two leads. One will hook up to the low speed terminal and the other will hook to the high speed terminal in the back of the motor.

My pole saw has lost power..I look at the motor and it is sparking like mad
ANSWER : Either the brushes are bad, OR worse iis that one of the armature windings has shorted or is open. Brishes are easy fix, shorted armature is more expensive.

Inducer motor doesn’t work. I need to replace it. Is installation difficult? Hvac company wants to charge 600 for part and installation. I dont have that amount. I’ve found the part for under100.
ANSWER : No installation is not hard with proper tools and safety. Please disconnect power every time you work on it. Just be aware these motors turn on through safety switches and stay on only if they create pressure vacuum on the tube that is attached to them and to a switch. before condeming it I would make double sure that voltage 110 and neutral are making it to the fan. Typically they will try to spin a little and heat up rapidly if bad.

Our furnace keeps shutting down soon after burner ignites inducer motor stays running wont heat until reset switch behind inducer motor is pushed
ANSWER : Sometimes a “Flame Sensor” gets carboned up and does not detect that the furnace has ignited, so it shuts down the fuel source. Might try cleaning that if so equipped.

Change from 230 to 115 volts – Flotec 1 Hp Deep Well Pump
ANSWER : Most Flotecs have a switch inside the motor housing that allows you to use either 220 or 110. You’ll have to take off the end of the motor housing to where the wires come in to see it. It’s usually clearly labeled. Of course, if you are already wired for 220, you’ll have to drop one of your hot leads. Good luck!
