I have a 1994 Mercury Mariner 115hp 2 stroke. The issue isstarting but runs rough and need to keep choking to keep motor running or itstalls in drive with water muffs on. List of work I did within in 6 months. I onlyput non ethanol fuel in.
1)Lower unit redone 2) new stator 3) new trigger 4)replacedcoil and wires 5) new plugs and wires 6)new starter 7) new battery and negativeand positive run cable runs 8) new fuel separator 9) new prime bulb and hose10)timing adjusted 11)new voltage regulator 12)new fuel filter
Ran rough after all with the wok so I thought missedsomething. Took to a large professional marine repair shop. Mechanics looksover and made adjustments but said all was good but running like a scaled dog andneed to redo carburetors and would cost $600 additional to do. I took home todo carbs have done many of times for outboards and cars. Took carbs apart usedcarb cleaner rinsed and cleaned. Meticulously put back together with certified carb rebuild kit. Put back onand no go same. Starts rough and still runs like a scaled dog. I runs with ashake and need to choke to keep running.
What am I missing? I think it is a fuel issues somewhere. I willadmit I did not change fuel lines from tank to engine or fuel pump.
