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 :

Your lawn mower`s carburetor regulates the ratio of gasoline to air mixture. If the carburetor isn`t getting enough air, the mixture has a higher percentage of gasoline, which can create black exhaust smoke. It`s possible that a dirty or clogged air filter is preventing sufficient airflow into the carburetor.
Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
If it`s clogged, the combustion chamber may not be getting enough oxygen, resulting in a too-rich fuel mixture that will cause the engine to run poorly and even spew smoke. The solution is to change the air filter, a relatively easy task. Blue and white smoke is the result of oil on the engine.
A burning rubber smell

If your car smells like burning rubber, turn off the engine and check under the hood to see if anything looks out of place. Chances are that the smell results from a belt or other part slipping and rubbing against the hot engine. If you can`t identify the problem, take your car to a mechanic.

A faulty or dirty spark plug could be the reason your lawn mower won`t stay running. It might produce the initial spark, but the spark won`t be enough to keep the engine running if the plug is clogged with dirt and oil. Spark plugs are usually located on the front of a push lawn mower and connected to a black cable.
What Type Of Oil For a Lawn Mower? While automotive engine oil, such as 10W-30 or 10W-40, can be used in a lawn mower engine, it is generally recommended that SAE 30 motor oil be used.
If your car smells like acrid smoke or burning oil, it could indicate a problem with the engine`s piston rings, leading to reduced fuel efficiency and even loss of engine power. Mechanics can diagnose and fix this issue by replacing the piston rings or valve seals.

I bought a new echp pb-251 blower last year. towards the end of last season the blower seemed to run sluggish. I attributed it to the cold weather and stored it properly with fuel stabilizer. Now here in Texas our lawn equiptment really doesnt stay put up for very long, and i use my leaf blower to round up my leaves during the winter. — Long story short, I had a problem with power and replaced the spark plug and air filter with no good results. I took the blower back to Home Depot and they charged me to have someone look at it. It was returned running fine with “carbureator adjustment screw out of adjustment as the Problem found”. Now it is two weeks later and after only using the blower one time i am having the same problem again. it starts and runs but has no power when you pull the trigger. Where is the adjustment screw on the pb-251 so that i do not have to turn it in to get charged for something that should work again. Echo I love your products I have bought three weedeaters from you and three blowers ….very dissapointed in this one.
ANSWER : Hi, there is a wire screen in the exhaust outlet that blocks up with carbon deposits. It can be removed and cleaned with a wire brush. If blocked it will give you the problem you have and also make the blower quieter than it should be. Regards Phil.

Even though I have the carb. set in choke, and press the bulb many times, it doesn’t seem as if and gas gets through. I eventually put the carb. setting in Run and pull the crank many times before it starts. The blower is 2 years old, used on about 12 lawns per week. The problem stared in mid summer. Any suggestions? Thank You.

I have a mi-t-m pressure washer in the ca-series.The problem is the motor shuts down at times with out any reason. The first time I used it was on a house with a well supplied water. It worked fine,brought it home where I used it with no problem. It was used twice that first year. I then winterized it.The second year brought it out to the same house,I was using it for about a half hour when it just shut off with out any notice. I noticed there was back pressure in the engine when I tried to restart it. Once that was released it would almost start. I waited about 5 minutes then it restarted lasting only about 10 minutes. I then brought it back to the store where I brought it. They checked it out, They ran it for about 45 minutes saying they couldn’t find anything wrong. I then winterized it. This year I did my house first.I ran it for an hour and a half with no problems. I went to another house to help him with the power washer. I ran it for about a half hour and the same problem happened as before when I was at the other house. It would run for only 5-10 minutes at a time before just shutting off. Oil level is good. what could it be?
ANSWER : Mi-t-m pressure washers have a Low Oil shutdown feature that turns off the motor, this is often causing similar problems on this kind of appliance.Have oil checked, if oil is fine , then the sensor that controls oil pressure and activate the shut down should be replaced.Electronic problems , such as a bad soldering joint for example, can also cause shutdown.Sometimes a faulty pressure pump can also shut down erratically.If I was in your shoes, as the machine had already been inspected by a technician, I would call Mi T M, and ask the warraty to be validated. There is 7 years warranty on Mi T M pressure washers.Mi T M can be contacted calling toll free at 1-800-553-9053 or using the online form. Call them , telling that the machine had already be inspected by an authorized technician, and discuss terms for an eventual repair or replacement of the unit.If my comment had been helpful, please do not forget to accept my solution.Thanks.G.

YARD MACHINE MOWER NOT A YEAR OLD YET AND IT CRUDDIES UP EACH NEW SPARK PLUG AND SMOKES, NOT RUNNING WELL. ITS RUNS REAL FAST AND THEN REAL SLOW, SPUTTERS. I HAVE ALWAYS KEPT AIR FILTER CLEAN AND OIL CHANGED. WHAT COULD BE THE PROBLEM? MY SON THINKS ITS THE RINGS AND SAID I SHOULD TAKE IT BACK TO HOME DEPOT BUT I’VE HAD IT FOR 11 MONTHS. WHAT SHOULD i do??
ANSWER : Return the mower if possible for warranty repair or call MTD with the issue. MTD mowers typically are good quality and should run like new for a long time with proper care. Depot may give you a 1-800 number instead of customer service so before you load up the mower talk to them. It does sound like a bad valve seat or rings either one is not typical wear and tear.

Bought a Ryobi weed trimmer CS26 from Home Depot. The second time I used it string broke both ends. Could not take it apart went to Home depot after 30 days they could not take it apart. They would not give money back. I Went home banged the string spool got vise grips finaly took off spool and replaced it with optional spool slid in string per directions every time I try to use it string flys out. What the hell? Now what?
ANSWER : Just cheap equipment. Mark it up to experience and do not purchase equipment fro home center or box stores ever again. This is just one of the many problems of dealing with the box stores rather than a full service qualified dealer. If you can find one in your area, patronize them. Not just when the box store lets you down but for everything. These type dealers are disappearing and are not being replaced and soon they will all be gone.
