So that's twelve thousand miles from motors I bought for $20, and two are still running good.
Cant beat that with a stick............. I'm assuming you are a FD fella..., I will be building me another as well, got an old Ryobi 31cc with a zama carb, bullet proof old engines, haven't been into it yet but I think I can make a good little FD set up with it.
