Who knows about 5.5 hp governor Honda power??

This may be common knowledge to all you guys but I bought a chipper/ shredder from Lowe's years ago. I remember the manual said something like ethanol free fuel only. That engine sometimes sits for a couple years between uses but will usually crank first pull.
I have since acquired a pressure washer from my sister that was used once, then it sat for a while, never to crank again. It was filled with regular pump gas. I couldn't get it to crank either. I cleaned out the carburetor (I thought) and there was lots of corrosion sediment in the float bowl. Back together and still no go. Repeated probably 10 times before I discovered, from youtube, the emulsion tube. I pulled it out and these tiny little holes were plugged with corrosion. I had to search through all my junk to find a piece of wire small enough to poke through these very tiny little holes. Put it back together and to my amazement, it cranked on the first pull.
Now I know why to use ethanol free gasoline.
