    Is this a new blower, or an older one? Sounds like a gunked up carb. If it's new, take it back to the dealer. If it's an old gunked up carb, try some seafoam. Also, check the exhaust port for carbon buildup. If it's got a bunch of carbon, scrape it out. Preferably with something wooden (Popsicle sticks are great).

    I've got a krb750 too, it's been a very good tool.

    If the carb gasket is bad it could be sucking air and that would cause major running problems.

    Sounds like the obvious place to start.

    Well duh. You haven't even fixed the obvious but you wasted money replacing a sparkplug that wasn't bad. This thread reminds me of the threads that get posted stating, "I sharpened the blades on my mower now it doesn't cut right" only to find out they put them on upside down! :hammerhead:

    Replace the carb gasket and the problem will somehow mysteriously disappear.

    A clogged fuel filter will do the same thing. So fix that gasket and replace the in tank fuel filter.

    Depends on which one it is....the one closest to engine can be a problem. Use some deep creep and spray around on where you think the gasket is bad and if it changes engine speed you found it. Is this a 4mix or 2 stroke? Check gas filter and screen in exhaust. If those are good start looking for carb adjusting needles.

    Have you take out the muffler to check whether you have carbon build up? 3 years is a long time. Do that first before you even do any of the more invasive stuff.
