    UPDATE to this delema..I got no help from Ecko but they have heard of this problem before.No help from the common fixs..I was so mad..The thing was running fine One Month ago.I took all the things apart that needed to be inspected.Then I took Off the starter cord assm.I flip flopped the blower everyway possible looking for anything funny looking ..All of a sudden I see this black tube coming out of the tank going to some small white can looking thing hidding in the case..It was all so small I got my needle nose plyers out and carefully sneaked the tube and canister out from its hidding place..It was a big ball of dirt.I sprayed it off with carb cleaner and it looked like new ,White..Put it back carefully and replaced the starter coil cover ***.Then I went into the house found the blower break down on Echo's site for the blower parts breakdown .Looked to see what the hay the part was,,part number 10 on the PDF breakdown and lo and behold it was a tiny vent..I also see it is on My Echo weed wacker..Well I went back outside and Fired that puppy up.Keep my fingers crossed and squized the trigger for full throttle and WaLA.She reved all the way up like New.So Now ME happpy.I hope this helps out some of you Blower Dudes out there..Peace Out.

The carb may need to be adjusted or taken apart and cleaned. Also check the throttle cable to make sure it hasn't been streched out.

    Some do not have the adjustment screw. Is there a fuel filter on this model? If it does, I would change that first. If not, carb will need to be pulled off, pulled apart, and placed in solvent for cleaning.

    Sometimes you have to feather the the throttle for a minute, and then give her a good squeeze. sometimes they are tempermental when first starting to run

My troy built riding mower won't run full throttle it only run at about half throttle

if it runs good at half throttle, it just wont throttle up it sounds like the throttle cable has slipped. you might try to adjust it to get full throttle back .but if when you turn it up to full throttle and it dies then you have a choke, carburetor, fuel line, fuel filter or fuel tank problem. hope this gives you an idea.

Leaf blower runs on half choke

My craftsman leaf blower ran great for 4 years.. It stop running on me one day while using it.. I replace the carb, muffler and fuel filter with a new one.. it still will only run when the choke is half closed and don't run good doing that.. I have also noticed oil around the plug and muffler. I have to use either to get it started and I noticed when I pour a little oil in the spark plug hole before cranking it seems to run loner but not at full throttle think it might be piston rings shot.

9.9 evinrude, yr 1990..runs like a new motor but wont throttle up past about half speed..once or twice it kicked in and took off but only for a few minutes then went back to half speed..sometimes it will...

Check the fuel tank for water.Squeeze the fuel line bulb and see if that gives a boost,and if it does you may have a blockage in the tank or in the carbs.If the bulb contracts when the engine is running,you have a blocked pickup in the tank.Check the vent on the tank is not blocked.The symptoms you give all lead to a fuel problem.Also.Check to plugs after you have run the motor.If one looks darker than the other.Change them both.Hope some of this may help you

My 420 with an onan runs great at half throttle, then bogs down.

Are you sure you did not get the jets in the wrong places when you cleaned that carburetor.

2000 Chevy Blazer Cranks but wont start...

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!
