Re: 100:1 Mix
Weird, Tom. I took my bikes out again today and especially the oldest motor from Thatsdax with over a thousand miles on it is running better than it ever has and I am not imagining it. The other one is running well, but not that much different... seems to have a little more pull on hills. But they are certainly not worse as in your case. And there is no way the gas was bad? Sorry it didn't work out for you, but I sure like it and will continue to use it.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
