A little Mac...don't remember the model number...about twenty years ago and I still get steamed thinking about it. Bought it to brush out some old roads into a firewood cutting area. Sixteen inch bar. Wouldn't start unless you threatened it. Wouldn't run unless you cussed it. Threw chains,bogged down,kicked back like a buggy whip,puked oil and leaked gas. Took it back to the saw shop. They worked on it. Went back the next day...same thing all over again. Took it to a different shop. Still the same,maybe a little worse. Roads still not brushed. Went to town,bought an 032 Stihl. Ran Stihl for about an hour. Took chain off of Mac. Tied about a three foot rope to the handle,spun around and around and around like those guys doing the hammer throw in the Olympics and sailed that little yellow POS off into a canyon.
