Just wanted to let you know what I think of your product, nothing better! I have a chainsaw bought in the mid 70’s and have run Opti-2 in it from about ’77 or ’78. I had to put a carb kit in it today and was amazed, there was no carbon on of the piston at all. The piston look as though there had only been one or two tanks burned. The biggest problem is other parts are getting hard to find. All my other 2-cycle engines have performed extremely well with Opti-2. I cut about 20+ cords of wood a year and while this is not my only saw it has been used a lot over the years. Thanks, Barry.
