New Stihl chainsaw model MS 250. Used once before.

Second use - cutting 12" diameter creosote telephone poles. Made 8 cuts, then saw stopped working properly. Saw starts, runs ok, but once you pull the trigger it bogs down, as if not getting gas. Fuel filter seems clean, can't detect any fuel hose kinks. I removed the carburetor and blew it out, as best I thought. I suspect something (trash?) is blocking the fuel, but I can't figure out what or where. Service center estimates $80 - $100 to repair. A new carb is $12 + shipping from Amazon..... I'm tempted to chance replacing the carb at this price.

I have no idea if cutting creosote material, itself, is relative to the problem.

The only reason that I mention this, Sonny, is that you didn't: Is the
chain properly adjusted and the chain oiler full?
