[QUOTE="a. palmer jr., post: 7642299, member: 14885"] I was told that the Echo saws have a fixed high speed jet, although a screw is there marked H it is only for fine adjustments and has only a one turn range. That's why the limiter is put on the screw. Turning it further than one turn actually doesn't make it richer, it's beyond the carb's limit. Like I said, I just read this but have had limited experience tuning Echo saws..I only have one Echo saw, a 330T. [/QUOTE]
