no i know its not the gas ratio.. i havent tried the spark plug yet. I tried vaccumning the air filter, maybe that wasnt enough. thanks for the inputs.
what works better than vacuming is using an air compressor with an air blower. done that billions of times to extend the life out of air filters on cars, trucks, lawn mowers, whatever! just be sure to blow the dust out of it backwards. not a bad idea to do any time you so a service check/tune up on your chainsaws, weedeaters, lawn mowers, ect.
