Well my Echo blower has stopped running. I did a carb rebuild, no fix, replaced the carb., no fix, replaced the fuel lines and in tank filter no fix, replaced the spark plug no fix and replaced the air filter. It seems as its not firing when pulling the string. I got a good gas oil mix I use the same in a Echo weedeater. Not sure what else to try not going to take it to the shop (4 weeks till they get to it). its a Echo PB200. Any help is apprecieated.
