Yeah, nothing like cross contaminating the fluids in your "official assembly" video. Frankly, I was shocked to see that this comment section is still open. Residual engine oil into the carburetor, then residual engine oil, and gasoline right into the hydraulic oil tank. And yes, I am well aware that these are ALL petroleum based fluids. But why add additional "x factor" variables into potential causes, should a failure in any one of these systems happen to occur? Aside from that, good video on the actual assembly. Thanks
