I just bought a Shindaiwa 488 new but old stock manual says 40:1. Called dealer because web site said 50:1, he said 50:1 ok 40:1 is better. He said the reason it's 50:1 is because some people can not mix 40:1 since all packaging is 2.6 oz per gal. I wonder if there is any truth to this?
Instead of waiting for these great guys to come back, {they won't}.
I thought I would bump them back to edumacate the new kids, and
the hard headed old ones.
