Weedeaters, Weed Wackers and String Trimmers - Choosing and Repairing

Tools needed to start a business

My first string trimmer/weed wacker was an electric Weedeater brand, with a curved shaft. I used a 100 foot cord and flipped it all over the yard, over bushes and plants and eventually got the lawns trimmed. The curved shaft meant lots of bending over and of course the electric cord was not fun at all. For a homeowner with a small yard, these two handicaps probably wouldn't be such an issue.

After making enough money to warrant purchasing a gas powered string trimmer, I chose a handlebar style, straight shaft, Homelite. It was a great machine, had tons of power and although a bit heavy, I really liked it and so did my employees. Great machine, lasted several years.

After the Homelite, we bought two Echos, gas powered straight shafts, they were really pretty light compared to the Homelite. Over the years, we pretty much stuck to the Echo brand in not only string trimmers, but also with our back-pack and hand-held blowers. The Echo is a good brand and it holds up fairly well, but we found that with heavy use they would only last a year or two before needing a ring job. Our gas/oil mix was always a bit rich, so that wasn't a factor. I really think we just used them too many hours.

Had always heard about the quality of Stihl products and my Dad has always had Stihl chain-saws, so we purchased a Stihl string trimmer. The Stihl has been excellent, a bit heavier than the Echo, but in my opinion a heartier, more heavy duty machine and it has been running well for several years now. We also have a Stihl hand-held blower, Stihl hedger and a Stihl chain-saw; they have also been wonderful machines.

Repair work - What to do when your trimmer stops working or won't start

If you have a new string trimmer that doesn't seem to have the power it used to when you bought it or if it has refused to run or even start, don't just take it to the local power store, you can easily fix it yourself.

There is a small metal screen in or before the exhaust manifold that clogs with carbon. All you need to do is remove the exhaust manifold, usually two long bolts, and clean the screen, what I would do was to throw it away, no more clogging. Put it back together, now try starting it, I bet it runs like brand new and you just saved $70.00 or more!

I am not sure if the equipment repair centers replace the screen or also throw it away, if they replace it, that sure would be easy money, when it clogs again after a few more uses. Some states, like California, probably require the screen to be on there, it is a spark arrestor.  So check with your local repair shop prior to tossing it.

Another money saving tip, let's say your trimmer is a bit older and you know the screen is not clogged, but it still has no power. Remove the exhaust manifold and look into the exhaust port, you should see, or barely see, the piston. If you slowly pull on the start cord, you should see the piston go up and down. Pull the cord and make the piston go completely up into the cylinder, you should not be able to see the ring, only the side of the piston. Now comes the delicate part, you will need a small flat sharp object, I use a flat blade screwdriver.  Carefully chip away at the carbon build-up in the port, being very careful not to scratch the piston, that would be very bad.

You are opening up the port, so the exhaust can flow freely. Using carburetor cleaner will help to loosen the carbon and then spray away the debris until the port is open and clean. I can't stress enough, not to scratch the piston, chip the carbon build-up away CAREFULLY. Re-attach the exhaust manifold and WOW, it runs like new and you probably saved even more money this time!

What string/line to use?

We really like the multi edge cutting line, it cuts cleaner and lasts longer than the regular round line.
