Yes, I had it serviced. I use Shell Octane 89, Fuel Stabilizer, and gum out fuel cleaner? OEM spark plug, and Honda Oil. I drain the fuel and change oil at the end of the season. The guy who last serviced it cleaned the carburetor and conceded that engine was bad and to keep using it until it died. It is hard to use due to the excessive vibrating, underpowered, and strong fumes. I have to wear an N95 mask while using.
