Had a bit of motor trouble at the end of the season. Seemed like the carbs or a carb was flooding. Good idle but when I put it in gear and tried to throttle up, it was bogging down. If I kept forcing it, it eventually "cleared" and would speed up and get on plane. This happened at times, and at other times started and ran up to speed fine. Other times when this acted up, I would shift to neutral, raise the RPM with the warm-up lever until it responded cleanly and then shift and take off.
Had an OMC shop squeeze me in to take a quick look. Spark and compression are fine. We took the boat to a local launch ramp and submerged the lower unit while still on the trailer. Shop owner (30 years in the business) ran it at what I would think was close to WOT and it ran and shifted fine. Power pack, coils and stator, fuel pump have all been replaced recently so the mech thought it might be dirty carbs. I have the time and like a challenge so I bought the kits. Sierra with the floats but know the cork floats are long ago replaced but not much cost savings w/o the floats.
So I get to pulling the carbs today. The sheet that comes with the kits doesn't say much. Clean it, adjust float, re-install in reverse....... I don't have experience so could use the advice of those that have.
Looks like 3 core plugs. Should I remove all 3? What tools and techniques are appropriate? Two on top
One on the bottom facing the bowl
I removed the high speed jet with a narrow screw driver
Pic showing the nozzle and orifices
These all show the top carb. Looks pretty clean to me so far as I have not started to clean it yet. Maybe I'll see more issues in the other 2. Please feel free to comment on any items regarding cleaning and re-installing. I have bookmarked a post regarding the link and sync and will be looking to make those checks later. Or, am I off-track and my running ploblems may be something else.........?????
Thanks to all in advance.
