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 :
We recommend the use of 84-90 octane unleaded gasoline with less than 10% alcohol content.
Clean the Exhaust Spark Arrestor Screen
As with plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gas flow, which leads to power loss.
This string trimmer has a 2 cycle engine so it requires a fuel/oil mixture. The TB25S requires a 40:1 fuel/oil mixture using an SAE30 oil.
One gallon of gasoline combined with 3.2 oz of two-cycle engine oil. Unsure of the age of your equipment? Use the 40:1 mixture. All of our handheld two-cycle units can operate on a 40:1 two-cycle oil mix ratio.
The best fuel for 4 cycle engines is ethanol free. Even though ethanol free fuel does not deteriorate carburetors like gas with ethanol, we strongly recommend, running the engine until the tank is out of gas, so only put into the tank the amount of gas you feel you will use.
Just Like Spark plug fouling, too much oil in the gasoline, inferior oil, a dirty air filter and/or continued operation at less than full throttle will plug the screen with carbon deposits. This prevents exhaust gases from flowing out, which leads to power loss or not running at all.
The clutch engages the clutch pads to spin the trimmer head. If the clutch assembly is defective, the clutch will not disengage the clutch pads, and the trimmer head will continue to spin, even at low speeds. If the clutch is defective, replace it.
All Weed Eater brand two-cycle gas trimmers use a 40:1 ratio of gas to oil. That`s equal to 3.2 ounces of oil to 1 gallon of regular gas. The gas should be 87 octane with no more than 10 percent alcohol. The oil must be formulated for two-cycle engines.
If you put straight gas in the tank, you may get to burn half of it, or you may just get to start the engine. With no oil mix in the fuel it will take oil from the base.
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.
If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
Common gasoline and oil mix ratios are 50:1 and 40:1. Meaning there is 50/40 parts gasoline to one part oil when mixed. The lower the mix ratio number the more oil per volume in the gasoline. To mix properly add oil to your gas can, then add fresh gasoline from the pump.
Unlike other four-strokes, the 4-MIX engine runs on a standard petrol-oil mix (1:50).
If a portable gas-powered generator is part of your hurricane plan, keep TruFuel 4-Cycle fuel on-hand. It`s ethanol-free fuel that stays fresh for two years opened and at least five years unopened, making it the perfect fuel for limited-use emergency generators. Four-cycle engines were never meant to process ethanol.
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the string trimmer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance.
The most common problem with a string trimmer is that the unit runs out of string. The string may also be twisted or loose on the spool. The cutting head may be dirty or the head outlet guide may be bent. An electric trimmer`s power cord, switch, or motor may fail.
Sometimes the spark arrestor screen can become clogged up itself. Common symptoms include lack of power, especially under load; poor acceleration; engine won`t come up to full RPM; and higher than normal “spit back” through the carburetor.
Poor Engine Performance
After the engine finally begins to start, it may tend to die out immediately if something is wrong with its spark plug. In some cases, the engine may run for a while then stop while mowing. Each time the engine dies, it must be restarted, which usually proves more difficult as the engine warms.
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.
The most common problem with a strimmer not starting is that there`s a problem with the fuel mix. Double check that you`ve used 40 parts fresh unleaded petrol to 1 part 2-stroke oil (40:1). Check the petrol you`ve used isn`t stale.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
Unless your tool instructions specifically say to store the battery on the charger, be sure to remove it after charging is complete. Overcharging can damage a battery and shorten its life, and not all chargers shut off automatically.
Charge only when needed and never overcharge The Trimmer.
Turn the high speed or main jet screw clockwise until the engine begins to slow. Then, turn the screw the other way until the engine begins to slow. Turn the screw back to the midpoint. Once adjusted, check engine acceleration by moving the throttle from idle to fast.

Wont start my blower will not start. I know the problem was the gas/oil mixture was bad because it also happened to my weed eater. i got all the gas flushed out and put a new set of gas/oil mixture. It worked fine for my weedeater, but I still can’t get my blower started. Any suggestions??
ANSWER : Take out the spark plug,spray in some starter fluid for engines. Then refill your tank with premium gas because the low end gasoline has too much ethanol in it and it forms water in the gas very quickly.Try to buy ethanol free gasoline if you can find it. Its better for small engines.

I have a Husky 350. It starts and runs until I give it gas, then it bogs down and quits. If I start it and just let it idle, it quits after 10 seconds or so. New plug, clean air filter, fresh gas.
Thanks for your help,
Dan
