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 :
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
As the fuel level drops, a vacuum begins to form in the fuel tank because air can get in to fill the space the consumed fuel occupied. After about 10 or 15 minutes, the vacuum will become strong enough that fuel will stop flowing to the carburetor and the lawnmower will die.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
Most riding mowers last between 500-700 hours, although some can run for as much as 1,000 hours if cared for and maintained properly.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
You Lose Power in the Middle of Mowing:
Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.
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.
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.
Check the Battery
The battery is the next stop when investigating a slow cranking mower. A weak battery cannot sustain enough charge to spin the starter mower and turn the mower`s crankshaft. Mower batteries last around four years, so one that is older may be ready for replacement.
Tractor may be starving for fuel.
Sometimes the fuel cap prevents the fuel tank from breathing. The fuel tank can develop a vacuum. This could cause fuel to stop running to the engine – causing it to stall. If this is the case, give it an hour or two, and the tank pressure will reset and equalize.
As a rough rule of thumb, a single-cylinder mower with 500-750 hours would be considered a high miler, but that`s not to say it`s all worn out. A well-maintained mower will go on and on, as said earlier, my own ride-on mower has about 1000 hours and still pulls its weight around here.
How long will a residential lawn mower last? The average residential mower is used for 1-2 hours per mow with 35 cuts per year. Based on that usage, a lower-quality line of residential mowers is expected to last 450-500 hours, while a John Deere residential lawn mower will last around 1,000-1,500 hours.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die
By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.
Changing the Spark Plug and Air Filter are good ideas, and are general maintenance items. The carb cleaner could also be sprayed into the carb through the intake. If those items dont restore power, there is a good chance your motor`s compression is low – and you need to rebuild it.
The factors that keep draining your lawn mower battery include damaged, loose, or corroded cables, an electronic drain, or cables that are attached loosely. Sometimes, it is as simple as the battery needing some maintenance. Other plausible reasons are faulty alternators, voltage regulators, and battery chargers.
The most common cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.
Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.
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.
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.

My tractor stalls like it is starved for gas although the gas tank is full. I,ve changed the fuel filter and the gas cap. I’ve cleaned out the gas tank, gas lines, and the carburetor bowl. The problem seems more acute when the gas tank is full or near full. At this time to alleviate the problem, I blow through the gas cap and the fuel filter fills with gas and it runs good again. But as soon as the fuel filter has no more gas, of course, it stalls until I blow on the gas cap. As the tank gets down to about 1/3 full, the engine runs OK. What else could cause this condition?
ANSWER : I had a similar problem with a sears tractor. close to the carbarator is a rectangle box with a rubber hose going to the engine block – remove the hose and spray carb cleaner in the hose wait a few mins and try again – its a vacuum for the carb

Having problem getting fuel to carb on JD LA 105 lawn tractor with B&S 19.5 gas engine. I replaced fuel filter and fuel pump but gas will not flow to carb. Gas flows from filter to pump and I can pour gas in line to carb and engine will run until gas runs out of line but gas will not flow through pump. Could new pump be bad , if so how can I check it out?

Need to replace fuel lines on my Troy Bilt gas hedge trimmer. Where can I get replacement fuel lines… or better yet… what size are the lines and where can I buy a few feet of the lines. Note: I have reviewed the parts assembly and it would seem to indicate I have to replace the entire handle assembly (Part #1) instead of just buying replacement hose(s). Any help to resolve my issue would be greatly appreciated and thanks in advance
ANSWER : Replacement fuel lines should be readily available at your local lawnmower repair shop. Your TroyBilt hedger uses fuel line that is 3/32″ (2.4mm) interior dimension, 3/16″ (4.8mm) outside dimension, with a 3/64″ (1.2mm) wall dimension.
Most manufacturers don’t offer replacement line, only fuel tank assemblies. Find your local shop, and try to get the TYGON brand…it is yellow. Tygon lasts the longest. You should be able to buy it by the foot for less than $2 per foot. You will need 2 feet of hose to replace both lines.

Make sure to clean the in-tank filter when replacing hoses.
Good luck.

The fuel lines have rotted out of the edger gas tank. How do I fix or do I need to replace entire tank with new fuel lines?Since there are no male fuel line connections exiting the fuel tank and just two holes where the lines were, I guess I need to replace the entire tank and get a new one with lines already attached. Thanks.
ANSWER : No you can buy replacement fuel line but you must reconnect the filter in the tank that line goes to the bottom of the carby then out the top of the carby to the inlet on the primer then out of the primer and back to the tank.

I need to replace to fuel lines on a Craftman 32cc trimmer. The old ones cracked apart. 2 of the lines look like 1/8″ OD one line looks like 3/32″ OD. Larger line looks like it hooks to filter, Smaller line to a fitting in the gas tank. I am assuming the smaller line ges to the primer inlet. My question is the lines penetrate the bottom of the gas tank. How do they seal. How do I install the filter and the fitting. I am assuming to thread the new lines in from the bottom of the tank and pull through the gas cap hole. Then I attach filter or fitting and pull back through. So do I pull the line so as to create a seal from the swell caused by the fitting/filter?
ANSWER : Depending on the brand of line you use, Tygon line is self sealing but seems to shrink faster then factory supplied because of the ethanol in the gas. The stone gas filter is designed to fall to the lowest part of the tank, not stop the line from falling out.

Which fuel line “port/inlet” on the Walbro wt-380 goes to the fuel tank? It’s on a Craftsman 25cc Gas “Weed Wacker” Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer bulb. The carb has two inlets for attaching fuel lines – one to gas tank, one to primer bulb. One inlet is on diaphragm side of carb (side with the two Low/High speed adjustment screws). Other inlet is on “reservoir?” side (side with air/fuel mixture screw). Which inlet gets the “fuel tank line”? (Other will obviously go to primer bulb. I found all kinds of diagrams on web but none that showed this. Your assistance is greatly appreciated. (Problem occurs when replacing gas lines and forget which line goes where:)
ANSWER : Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does
