Blower wont start

HELP! I left my backpack blower (stihl br420c) out in all the Fay rain in the back of my truck with the muffler hole up. I drained all the water i can out pulled the plug and left it out for a couple of days with piston up and down to expose ports. Ive changed plug and it wont start. Im getting a blue white spark. I put ether in cylinder and it still wont light. Poured a little gas in cylinder wont light. Dont even get a puff of smoke. Thanx for any advice

shouldnt have water in gas although i havent checked it. Left it in rain many times cause i clean parkinglots after work. Never done this before. First it fell over and got water in motor though. It wont fire on ETHER is what i cant figure out or fresh gas in cylinder. May be the simple fix is to drain out gas in tank.?!
