Four months later, the new fuel tank arrived!



Hmmm, which sticker did I go with?



My plan was to simply replace the tank and see how this went. After researching, it was looking likely the fuel leak was causing the surging issue. When the throttle was cracked into the choke, the engine would smooth out, leading me to think that the carby was not the issue and that the engine was simply running lean due to a lack of fuel flow. So, I hoisted the mower up onto my workbench, the back of my daily driver.



First step, I removed the air filter cover, followed by the throttle cable.



I then went to remove the fuel line from the tank, which I immediately found the problem...................





So, the leak was caused by a perished and cracked tank outlet, which finally separated when I went to remove the clamp and hose.

Next, the three top mounted bolts and one side bolt were removed, and the tank lifted off the engine.



New tank ready for install. At this point I realized I had the later version of this tank, which offers a slightly bigger volume and extends further rearwards. Thankfully, it still fitted this engine. The larger fuel volume is not a bad thing, from experience, these engines are pretty thirsty.



While I was this far in, I wanted to take a look at the carb, which meant removing the air filter housing. That housing was changed to plastic on later engines. While it was off the engine, I went ahead and cleaned it up too. I then removed the old fuel hose from the carb. Also note the breather hose comes away from the metal pipe and remains with the housing.





I then removed the bowl, which is held in place by one single nut which also functions as the main jet. You will also note I had installed the new hose to the carby.



The bowl was surprisingly clean, no sediment or varnish.



Main jet / bowl nut, which was cleaned.



Because of the condition of the bowl, I decided to not go any further. I did however replace the perished bowl o-ring, and replaced the main jet gasket, both included in the kit.



The old carb inlet gasket was in bad shape and was replaced with the item in the kit.
