    so i just took this thing apart,looks like i can space the fan out closer to the housing and maybe put a 1/4 screen over the inlet.
    any more ideas?

    If I'm not mistaken there is a filter inside of these and it could be blocked up OR the plastic fan blades could be wore down OR both OR the assembly could be leaking at the barrel causing the vacuum leak ! Good luck !

    I made one a few years ago, a DIY project.Sounds like the impeller is shot.If yours has a 'plastic' one replace it with a metal one.

    You gotta replace parts. Remember, when you are running that thing, you are basically sanding down the impeller blades. Take the whole thing apart, clean the hell out of it and replace everything that looks worn.

    Brad --- have you checked all the seals to make sure they're air tight -- maybe a small leak could reduce the suction.
    I'm sure you have but might be worth a re-check.
    I made one a while back and it worked good but the blower would like to fight me to start.
    Echo is a good blower -- mine came out of a dumpster and I should have left it there.
    Cheers Mike

    the seal look ok.but the fan looks a little beat up.i will clean it up and try to space it out closer to the housing.it will also test some screens over the inlet.i will test it by timing how long it takes to empty a 1 gallon bucket. thanks
