Short History:
I purchased the boat it had a new fuel pump put on it and the owner told me it just got a good bill of health from a shop. I took it out to the lake and it bogged down when trying to open it up. However it would intermit some. I narrowed it down to the # 3 cylinder not running. It had great fire (blue) The carb bowl was EMTPY. Very easy fix of course. I cleaned the carb and replaced the needle and seat. Took the boat back to the lake it ran wonderfully. (Idle kinda rough and tries to die going into gear) I put some Evinrude Fuel system cleaner in the tank to try and prevent # 1 and 2 carb from doing the same thing. At the end of that day it started flaking up again. I went to the lake a week later and it was bogging again. I was already a mile into the lake (I had to get there at steerage since it was a no wake zone) After approx. 30 minutes it opened up and ran great for a half hour. I stopped to drop the top on my boat and it went back to running cruddy again. Within the hour if I did anything but idle it would die. I was towed back in. Here are my current symtoms.
All cylinders are fireing. (bright blue) I removed the screw from the carb bowled. All full of fuel. With the engine running I unplugged each spark plug to look for the cylinder that wasn't hitting. I was back to #3.(bottom) Retested the fire.(blue) Carb has fuel and when spraying fuel directly into the carb, the engine slows instead of speeding up. It appears that the #3 cylinder is burning fuel. If I pull the plug right after running the engine its wet. As if it where flooding?? maybe the float is of but would it not be intermitting? Seems it would always have the problem. Fuel filter is clean and new, bulb gets hard Im not exactly a newb to outboards but Im a little stumped. Any ideas?
Also I hooked a timing light to it to see where it was at and when I pull the trigger on the light it slows the motor WAY down. That isnt right is it? Also how do you hook a tack to this engine?
