Hello Everyone! I'm new to this forum. I am the original owner of a 2002 9.9 powerthrust Honda that I use as a kicker for my 21' fishing boat. I recently replaced the water pump that was pretty well gone. I found all the rubber pieces in the screen area and pulled the thermostat while it was running to make sure any rubber pieces were flushed out as well.
The engine is running rough. It was starting this before the impeller changeout, but now it simply won't idle and stumbles, misfires and generally works like crap. What I've done so far:
1. Try different fuel;
2. Pull the plugs inspect and verify gap at 0.30;
3. removed the carb entirely - pulled the float bowl off, shot out all the orifices with carb cleaner. I did not disassemble the floats, or remove jets.
4. Put it all back together again. Still runs lousy.
