So I have a 2001 2 stroke 90hp serial 0T262997 with a mysterious misfire/rattle at low rpm that leads to stalling. I changed the rectifier as per a lot of research into this engine to no avail. So I proceeded to clean out the carbs in hopes it would help. My question is that, after a carb cleaning on these oil injection engines do I need to premix the fuel? When I reattached all the fuel lines and primed the bulb, the fuel filter seems to be filled with just straight gas and no 2 stroke oil. I was going to start the engine, but now im thinking that possibly my fuel pump isn't mixing the gas right which would cause this issue? This is my first outboard and im trying to learn it all on my own. I have read the entire service manual, but can't seem to find any info on it. Thanks in advance.
Current procedure: changed rectifier and replaced connections going to yellow wires(melted), decarb with seafoam (2 runs), new fuel filter, new marine starting battery (old owner had a dying deep cycle which I believe caused the issue), new spark plugs, fresh gas, cdm jump all checked out fine (7/16 in) & resistances, compression (cold 120, 122, 122; warm 122, 125, 125).
