I have a 1993 johnson 150. It sat up for about 6mo. Now it won't start right up. After leting it set for a little while it will eventualy start. The plugs are wet. I installed a new set & it started right up. I let it set for a day & I tried to start it again & it won't start. The new plugs were wet again. I have new gas in it & I have run almost a whole tank thru since it sat up. After it starts it will run good & start good until it sits up over night. Any suggestions?
