After dealing with removing a fuel tank, cleaning the tank, changing the filter, and putting everything back together, my efforts were a failure. My four-wheeler was still dying, and now became really hard to start. I had to do more. I had good spark, but I still needed to check the coil to determine if it was weak.
I checked the coil. The ohm reading indicated it was good. That left removing the carburetor and either rebuilding it, or replacing it. This led me to looking at the price of a new carburetor, or a rebuild kit.
The manufacturer price for the carburetor was $450. A look at Amazon found a rebuild kit for $33, or a replacement carburetor for $32 delivered to my doorstep. I crossed my fingers, after reading reviews, and ordered the carburetor. The next step was the arduous task of removing fenders, the fuel tank, the air filter housing and finally: the carburetor.
The carburetor was delayed in arrival, but finally arrived late Monday morning. Installing it was the reverse of removing it. I finally reached the point I could check the operation around 6:00 pm. It ran like a champ, so I started replacing all the parts required to complete the assembly. I finished right before dark, put up my tools, and breathed a sigh of relief.
So, I have to give the engineers credit for designing the machine. The details required to design it, insure the operation, have all the parts either manufactured, or bought, and mass producing the machine is an accomplishment. The task is way beyond my expertise, and I'm impressed.
