    Hi guys, im new to this site, very informative!

    I have a echo blower pb755 that is obviously having carb problems, it looks like its running rich because a new plug will be wet and fouled in less then a day and there is also a bit of fuel in the air filter compartment. Any ideas on how to fix this? or should i just replace the carb? the blower is around 2 years old. Thanks for your help!
    P.S. im also having studdering problems with a couple of redmax blowers that are sitting in my storage because i gave up on them, i guess i should post a separate thread for that, but if anyone has experience with redmax 7001 let me know, thanks.

    I do a lot of repairs on Echo and seldom need a new carb. The first step is find the adj. screws and adjust it. Be sure the muffler side ports are clean and if it had spark arrestor take it out.

    I only see the idle screw, do you know where the adjust screws are on this model? and what do i have to do to adjust it? ive never done this before so your help is really appreciated. And yes the port is clean and the spark arrestor is out. http://www.echo-usa.com/pdf/documentation/PB755T_P108_12_070909.pdf here is the parts manual, if you look at the carb page could you tell me where the adjust screws are?
