Stihl 028 AV
I am working on a neighbor’s 028 AV. It was running poorly and appeared to have fuel system problems. There was a lot of fine saw dust in the fuel tank When I disassembled the carb, I found a piece of foam gas filter on the end of one of the needle valves.
I cleaned and flushed the fuel system including tank vent and fuel line. Replaced gas filter, disassembled and soaked carb in cleaner, reassembled set at factory settings and started it with with fresh gas. The saw runs but as time passes it seems to starve for fuel and stall after 30-40 seconds.
The standard adjustments don’t seem to be working. I did not replace any carb components since they all looked to be in good shape. The screen is clean.The tank vent was plugged but is working now.
Any ideas would be appreciated.
