Pulled my saws out today to dump out the fuel and refill with fresh fuel and stabilizer for the winter. My 3 year old new never used 7900 powerhead had only a partial tank and It was full when I filled it last fall.
So with the new fuel I start to pull it and notice something misting out the right side by the AV spring. The fan is spitting out what looks like fuel vapor out from the cylinder fins. Get it started and it smokes like a banshee out the muffler. Looks like a smoke machine. Also black oil (not bar oil) running out the front from under the muffler.
After a minute or two the smoke clears up. Must have been mix oil running out the front although I use Mobil 1 and this oil was black.
Did the fuel get pushed into the cylinder through the carb some how?
Did not have this problem in the past with this or any other saws.
