Pricing for Farmertec kit and repairs at the end of the video. There once was a time when you could buy a knockoff HS 81R hedge trimmer for about $160 but I haven't seen it in a year or so. I assume STIHL has put the crackdown on the sale of this kind of stuff in the U.S. as they should.

Might have mixed up Bosch and NGK spark plug numbers.

This is not the 4-mix, it is the original style 2 cycle. The 4 stroking term doesn't exactly apply, but there is a tone change when mixture is correct.
