Howdy folks,
It's been a while since my last post because my engine has been running great! That is until a few weeks backs it started doing some crazy dance at speed, losing power, then running fine and then barely letting me accelerate. Mind you this was after a full day of running fine. Then noticed it would barely accelerate and then finally would only idle. Before all this occured it's been about a year of great running. About a year ago I replaced the following:
- Regulator
- Power pack
- stator
- fuel lines from the water separator to motor
- ignition key unit
Since my trouble a few weeks ago, it feels like a fuel delivery issue, so i thought carbs. Rebuilt all 6 from the metal plate forward (in other words, did not take off the butterflies or the plate as to avoid having to re-sync). Then I went out all day yesterday, had full range of throttle and probably run for a good 5 hours. Came over this morning and hooked up the hose to fire up before hitting the ocean (habit by now) and would stall on any throttle up. Thought maybe i boogered something up with the carbs or the float, so went back into each and reset the float height correctly, some were a bit off. Took to the local lake and immediately having the same issue of weird hesitation all through the throttle range. It would get up to plane, run fine, then start acting up again without any additional throttle inputs.
Am at a bit of a loss on what to check next. In my driveway with the muffs on I noticed 2 things:
- If at the motor, I manually open the butterflies on all 6 carbs, revs go up, no hesitation
- If at the motor, I manually advance the timing, the motor dies
Thoughts? Anyone have something similar happen and find resolution? At this point i've essentially replaced all the electronics on the motor. Carbs have all been hit with rebuild kits. Maybe fuel itself is an issue? I noticed the water separator was a touch hazy.
oh, and starting the motor. Easy. Fires right up first turn of the key with minimal choke.
