It would then start and idle with choke on but would die when revved up. Did carb overhaul, re ... Read more placed a couple of bad looking gaskets, and cleaned everything up. Same results. Ryobi blower had a Walbro Wyc-8 carb which has no adjustments I could find. Finally bent the metering lever up to allow more gas in. Had no idea how much to bend it. But when I put it back together it runs pretty darn good. Have to keep flipping the choke on until it warms up, but I\'m not sure I want to take it apart and try bending the lever more. Probably would mess it up.
