Today we will be removing and cleaning a carb from a Westinghouse ipro4200 generator to clean it out and ensure good operation of the unit. This one has a stutter to it, with possible contamination. One major culprit is forgetting to drain the bowl after use, causing gas to rot on the bottom of the carb. Ironically, this bowl draining is the first step in the carb removal for repair.
This particular generator model has a different setup for the airbox. Also, its an inverter generator with an electronic governor though this presents little different to the process though they are indicated in the video.
With the carb separated, the bowl is first removed to reveal any initial contamination possibility, this didn't look bad at all in the bowl. The float and needle assembly is disassembled, followed by the emulsion tube. I do avoid to remove the pilot needle on these small carbs if its not necessary, we will find out with brake cleaner and compressed air if this is the case. A spray pattern confirms this. If not i would have to pull the plug, count the turns in, and pull the needle to clean that section out. All areas of the carb are inspected and cleaned with brake cleaner and compressed air. The other small pieces are also cleaned in this manner.
A small amount of metal polish on a qtip is used to clean up the needle seat to a shine as well to ensure that the float will make a good seal. If the float needle is malformed it will need to need replaced from a rebuild kit.
Rebuild is the reverse of disassembly. The bowl should be placed back on in the same position that the drain can be reached as the factory set it up. Before installing the carb, if the failure was gas rot, ensure to drain and flush the tank before putting the carb back in.
