I have a 2 stroke Ryobi trimmer, Echo chain saw, 70cc small Yamaha bike,
and formerly an MTD snow blower. With basic maintenance and good fuel
mix, and some RTFM they all start & run great. The small ones are rather
picky about the starting procedure, esp the Ryobi, but it's right on the
label and if followed, they start with no drama. They're lighter,
simpler, and make more power for their size than a 4. But as ya'
probably know, the torque & power are in a narrower, higher rpm range.
Good for something you tend to run WOT. Don't think it would be great in
a lawn mower.
I buy Yamaha's "Yamalube 2S" for the bike, and use it in the others,
too. Supposedly semi-synthetic. It burns a lot cleaner than the usual
power equipment-grade oil.
