Hope weedeaters fit into this category...

 

  Iv'e seen this problem 1000 times and hundreds of opinions on how to fix...

 

My Royobi only runs when almost on full choke,(, and not to well at that )    Iv'e bought the carb kit,,, same problem...  Iv'e replaced the filter and fuel lines No luck..

 

 This is why most people just throw them out and buy new... I have fixed a few of them in the past.. But to run good one day and not the next..?????  or ever again..!!

 

One thing I noticed is that there are air bubbles in the fuel lines,, which could very well be starveing the amount of fuel,,Hence needing to be almost on choke...Not sure... They vibrate and get flipped around so much during use ..

 

                                            Any Experts out there...??????                                sodi

No! But have found that the fuel lines often need replaced and the primer bulbs too .
Mine disappeared last year? And I bought the cheapest Stihl I could and am very pleased.

Most of the shops around here pretty much just replace the carburetors on the small engines like the weed eaters.  I will usually take one apart and clean it but if it won't run right after that I order a new carburetor.  There are so many small orifices and you can't be sure you have them all clean.  Most small Carburetors are under $30 although I have found a few quite pricey.

The most practical thing to do on these newer pieces of equipment is to replace the filters lines and get a whole new carb. It actually costs more to rebuild them than what it is to replace the whole carbs. Many are epa compliant and are non adjustable so they pretty much force you on a new one anyway.

I've had some success in cleaning carbs on these smaller engines.  The greatest success was an Echo PB400 backpack blower I found on CL for $25.  The seller said that the repair shop wanted over a $100 to replace the carb and he couldn't see spending that much on it.  I bought it and took the carb apart and cleaned it and blew out all the small jets.  Been using it for two years now and it runs great with no problems.

I was telling a co-worker about a weed eater I had that wouldn't run right....bla, bla, bla.

He said I should check the screen in the muffler. Sure enough it was caked up and almost solid with crap.

I removed the screen and soaked it in gasoline and scrubbed it with  wire brush. After I had it cleaned up and re-assembled it ran like a top again.

If you run a weed-eater or most any 2 cycle engine less that wide open, they have a tendency to clog up the muffler screen,

Had this very thing happen with an old Homelite that I ran too rich.  After cleaning the "spark arrestor" it was fine for a couple of years.  Eventually I got sick of fighting it and replaced it with a Stihl.

most of the ryobi weed eaters had 2 mixture screws  , high & low revv , & some times with vibration they would get out of wack & were fiddly to re-trim to or tune

I know this is sort of a old post but wondering if Weed eater is the Weed eater brand string trimmer or is Weed eater a lump all machines that use line to trim ?

 

Figure most people buy the 87 octane pump gas with 10% or 15% Ethanol in it, It is a known fact that this stuff will not store more than 30 days in a can straight from the pump. If you plan on storing more than you can use in one outing treat it with a product like Stabil. Mix the oil to the correct ratio per the owners manual don't put in a little extra oil for good measure.  

 

First thing people do when having problems with a 2 stroke engine is mess with the carb all well and good but if gasoline was left in the tank for a extended time there is gum in the tank and cleaning the carb or replacing it a thousand times will not help until you get that filter out of the tank and either clean it with a carb cleaner or what I use is lacquer thinner or replace it also get the gum out of the lines.

 

I have never ever seen one of those little carbs that didn't respond to a real good cleaning in thinner and blowing it out with compressed air.

 

I have a Echo 160GT AE that will be 30 years old soon as it was a fathers day gift in 1985. Still runs like a top and starts very easy every spring and all summer long.

unless you know how to fix that problem :rocker2:

 

My new Ryobi I bought a few yrs ago wouldn't not run worth $.02, remixed gas, adjusted carb, just would not rev up high enough to keep head moving when trimming. I did some "fixing" so I could adjust mixtures screws, turned both 1/2-3/4 turns over factory setting. Now it runs like a scalded dog....like it's supposed to.

 

I think the little ceramic style filter inside the tank also get slugged up......usually over the winter when people do not drain or properly winterize thus starving the engine for fuel.
