Hey all, great resource here. First time poster but have been using the search function often.
I bought a 1996 Johnson 25 HP (J25TKLEDC) this summer to power a 13' Whaler. When I was shown the motor, it started right up. After bringing it home, I did a few PM things to get it into a little better shape - new plugs, wires, and thermostat. I mounted it and went out for a few rides, after a little bit of a rough start first time in, she ran wonderfully. Cruised out to LIS and back and had a blast.
Third ride, motor started to act like it was being governed. Wouldn't rev any higher going from 1/2 throttle forward. Was stuck right before getting onto plane. So, tried a bunch of fuel line fixes - new tank and line, new fuel filter, still the same. Ripped off all three carbs, rebuilt them (and actually found one with a bunch of schmutz in it, so I was optimistic at this point.)
Put the carbs back on, motor fired right up. Ran it at idle for 10', revved it up, back down, sounds great. Then, got busy (new job, etc. etc.) and a week later go out to test it out again. Starts right up... then dies. Then starts for 5 seconds... then dies. Then won't start. Let it sit a bit, go back, same thing.
Now, moved her into the garage, and can't even get her to start up once (I have a water tank to run it in). I'm running out of ideas. Spark, compression have been fine since I bought it. Even ripped off the oil mixing unit and am running in pre-mixed. Anyone have any ideas I could be overlooking? I hate to bring this damn thing into a shop after all this work...
Thanks a ton,
Brendan
