Fuel, engine is not getting gas when its under load. Plugged up carb would be my guess.

Take the carb of the unit and give it a good cleaning. One of the jets is probally gunked up. That blockage is causing bad fuel flow to the engine which is causing the problems you are describing.

If you start it and it reves then goes dead try tapping the carb continuously, if it continues to run the float or needle valve is getting stuck. The carb most likely needs a good cleaning.

I agree with the blocked up carburetor responses. The engine is getting just enough fuel to keep it running, but when its under load and needs more fuel, it uses up its small supply quickly and then stalls out.

Thanks for all the good ideas. The blower is about 12 yrs old,gunked up carb sounds on the money. I'm going to take everybody's advice and clean out the carb...good project for a winter day. Thanks again for all the help.

Actually it's a better project for a summers day. That way it runs in the winter when you need it. Good luck with teh carb cleaning. Hope it solves the problem.

Is there any carb cleaner/gas additive that would help?

New fuels with ethanol are tough on old equipment especially. Try using startron and stabil in your fuel can

Potential quick fix as it happens to mine almost every year:

Drop the bowl from the carb if you can. Mine has a screw on the bottom. Using a wire from a Christmas ornament (the PERFECT size and stiffness!) push up through the hole that leads to the needle valve at the base of what was at the bottom of the bowl. One or two pushes always cleans out the piece of crap that inevitiably finds its way in there every year and she runs like a champ.
