Fishbowl wished I could help ya out. Not knocking Toro..But from my experience is after going thru so many different makes is? Next time buy an Echo. Hope ya get this one running.

 

Sage wisdom here. Buy the Echo and you won't use anything else.

Besides, I did my research before I purchased it. It came highly recommended and was endorsed by 8 out of 10 illegals.

 

Be sure dobbers have not plugged the exhaust.

 

You should have two adjustments on the carb, 1 is idle mix, the other is high speed mix. Sounds like high speed port is plugged.
Did you try running it with the choke part way or full on.

 

Agree with SlickWillie. Gave up working on mine one time so took it in for repair and it was just exhaust plugged with muddobber.

 

tried running it withe the choke closed. it would idle and as soon as i opened the choke it ran right for about two seconds.

 

spark arrestor gummed up........

 

Yep!

 

I have found this to fix several brands of weedeaters. The cylinder head bolts get loose and you lose compression. I had to pretty much disassemble them but after I put some loctite on the bolts and tightened them down they ran fine.

 

mine is the same way, only way i can keep it running is to run it half choked for about 10 min then she runs fine , ah till i stop it then gata do the same routine all over.

 

That makes sense Terry...........the engine running heats up the cylinder head causing expansion creating a seal thus increasing compression.

 

Not sure if you got it fixed or not, but I had the same issue with my Echo. Idled fine, but would bog out really bad under throttle. On the Echo's, if you take the exhaust housing apart there is a little screen that fits over the exhaust port. It will become clogged up with carbon, unspent oil, etc. You have to clean it with some gasoline/carb cleaner and a wire brush, reassemble, and your back in business. The clogged screen filter will prohibit exhaust from exiting, thus leading to it bogging down under throttle. Hope this helps.
