    Check it for constipation--blockage of the anti spark screen.

    How long has it been since the in tank filter has been changed out? It's worth a look.

    May be carbon build up in exhaust port.

    What's the model on the blower? I took a look at a couple of RedMax HB blowers and both that I chose had adjustment needles.

    You might also check your suction side fuel line for any possible leaks. I've found this to be the case on occasion. At idle the unit will run but when additional vacuum will allow the the fuel line to suck air. Not likely but worth a check.

    Additional: A soft fuei line(usually in tank) can collapse under vacuum, thereby cutting off fuel supply.

    The carb prolly has j(d)unk in it necessitating some compressed air after a good cleaning. Check the fuel filter first.
