Calcruiser, this crap ethanol fuel is murder on carbs. On top of that the fuel just goes bad after a couple weeks. If my unit is going to be stored more than two or three weeks I treat my fuel with one ounce of sea foam for every gallon of fuel. I then run the gen to make sure the system is treated. I use sea foam over products like stabil because sea foam cleans your system as well as stabilizes your fuel for storage. The one time I forgot to do this my pc sat for two months untreated and my carb was gummed up. As you know the carb is about $ 300 and can not be rebuilt. And if you can’t do the work yourself add another 150-200 for labor. However I found a work around. My gen would not start at this point so I removed the spark plug, cut the fuel line to the gen and submerged it in a container of sea foam and hit the start button. Once I had sea foam pumped thru I let it sit for 2 days. Now with the hose reconnected I pumped fuel into the system using the starter, replaced the plug and hit the starter again. Oh it spitted and sputtered for a several mins, but then leveled off and runs like silk.
Side note, before cutting the fuel line I used a clamp to shut off the fuel so I wouldn’t drain the tank. I obtained a brass splice at Home Depot along with hose clamps and all is good.
