Thanks everyone. I made good progress today. All the trimmers are running. But both FS85s need carbs. Same with both MS180 saws. Funny thing is, they all have the same model Zama carb. I had to replace the one on my Dad's saw a while back too. Even a trip through the ultrasonic cleaner did them no good.
