When I wore out the saito 100 on my Ucando it had about 40 gallons through it. I didn’t even notice how bad the front bearings had gotten until someone else brought it to my attention.
The saito was running flawlessly up until the time I decided I better not push my luck and have it looked at.
I brought it to a hobby shop that rebuilds engines. A few days later he called me and said, “This engine must not have been running for you”
I told him it has been my most reliable and best running engine. He said it looked it had sat on the bottom of the ocean for a year.
The front and back bearings were badly rusted, the cam had grooves worn in it and the cylinder wall was scratched. He absolutely couldn’t believe this engine was running at all, never mind running good.
Seeing others have had the same problems it makes you wonder is it me that’s doing something wrong, or is there something else going on?
