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 fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the leaf blower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
If the piston rings or the cylinder are worn, your blower will lose power. These parts can become damaged for many reasons, such as running your blower with an incorrect fuel ratio. The most common reason to replace this part is because the piston rings are worn.
Echo premium Power Blend TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo engines sold in the past regardless of ratio specified in those manuals. 1. Fill an approved fuel container with half of the required amount of gasoline.
A faulty ignition coil will normally only fail once the engine has run long enough for the coil to become hot. If you discover that your blower is dying after it runs for a little while (basically until it gets hot), your ignition coil may be faulty and will likely need to be replaced.
For starters, the best backpack leaf blowers run for a long time: 30 to 60 minutes for battery-powered models and even longer for gas models, provided you refuel them. Most battery-powered handhelds run for just 12 to 15 minutes.
There may be old fuel in the tank.

Leftover fuel in your leaf blower is one of the primary reasons a leaf blower won`t start. Gas left in the tank for 30 days or more can deteriorate, causing the engine to stall or not start properly. If left for 6 months or more, the gasoline can turn into a thick sludge.

For example, the DPB-2500 with a 2.5Ah battery being operated on non- stop turbo mode will run for approximately 9 mins, 15 mins on high speed and up to 90 mins on low speed. 9.

Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog the fuel filter and cause the engine to stall.
Maintenance of gas powered leaf blowers produces toxic waste like fuel filters and contaminated air filters. Blowers erode, compact and dry out soil and harm plants, microorganisms and pollinators.
Oil mix ratios explained

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.

Blower motors are designed to last just as long as your furnace itself, anywhere from 10 to 20 years. Just as with any HVAC system, the better maintained and serviced your equipment is by experienced HVAC technicians the longer it will last and the fewer repairs you`ll face.
Damp, Wet Or Soaked Through

There is a difference. If the leaves are damp then it shouldn`t be a problem, a little wet with a powerful jet will still work well but if leaves are soaked then best to leave well alone until they have had time to dry a little.

A good school backpack should be durable enough to survive the wear and tear of at least four years of education, as well as weekend getaways and trips back home.
If your question refers to leaving the charged battery in the blower, yes you can.
Some cordless leaf blowers last for 15-20 minutes, while others can last over an hour. If you have a large yard, choose a cordless leaf blower with a long life to its battery to eliminate the need for a recharge midway through your session.

sounds like you have a bad Ignition Coil (Module). This is how they act
when they start going bad. When they get warm, they quit. Some will
last up to 20 minutes before they shut down. You can sometimes find a
used one pretty cheap at a small engine shop.Jim

I have a PB251 that I purchased from Home Depot as a refurbished unit. It has new plug, carb and all new filters. PB251 runs fine with a full tank, but when down to a half of a tank it stalls out and won’t run, until I top off the fuel tank again. Once again ALL filters and cap on this untit are NEW. Any ideas???
ANSWER : Its possible the gas pickup tube inside the tank is bent and not reaching the lower tank,this is just a flexible tube in the tank,otherwise,loosen the gas cap when it kills,sometimes they go bad and create a vapor lock

Will only develop power (and run somewhat properly) when the choke is engaged about 90%. Starts fine.
ANSWER : Sounds to me as tho you may have a loose carburetor or another part that is letting air into the system. Check all bolts and screws for tightness. Also, you may need to clean the carburetor or put some cleaner in your gas. Not too much, only about a tablespoon, but check the screws/bolts first.

My blower only runs with 3/4 choke even after warm up.
ANSWER : Look on the carb for 2 screws side by side. where those screws go into the carb, it will be stamped with an “H” and “L”. Open the screw that is next to the “H”, counterclockwise about 1/4 turn at a time with the engine running, that should solve it.
