Got a 2005 25hp JOhnson 2 stroke 2 cylineder motor with a problem. Motor has ran fine since new, but the other day I ran out of gas. Tank still had a little bit of gas in it so i cut the hose at the clip and stuck the hose directly into the remaining gas. Made it back fine, but later that day after refueling motor kinda started spitting back at idle, and bogs upon trying to go full speed. On the muffs it kinda kicks in neutral and will eventually die and cut off, especially if you push choke all the way in. Motor has 140 psi comp. on both cylinders. but I have noticed both plugs seem very wet, not a brown crisp like before. I have personally had carb off twice and cleaned, and professionally cleaned once, and it still does the same thing. any help greatly appreciated.

Re: 2005 25hp Johnson

^^^ very likely your problem, but also just ensure that when you re connected the fuel line that all connections are tight, and there are no air leaks present in either the connection or line. Possibly nicked it with your knife?
