So I ended up with a 545 that was thrown in on a deal. The previous owner said it never ran right from the day it was new and his dealer wasn't much help. It was from a tree service business and judging by how dirty it was, it had been ran quite a bit, which is a surprise as it would have been rather aggravating with the way it runs. It will start right up and idle fine, but if you mash on the gas it will die. If you slowly give it throttle, it will rev up and seems to cut ok. According to various youtube videos, I let it idle for over three minutes and then did the 90 second cut at full throttle. It seemed to help, but still isn't right. I've cleaned it all up, changed the air filter, spark plug, and fuel filter. Any ideas? Thanks, Cody
