motor is hard to start,will not idle,kicks sputters and stalls at high rpm.carbs have been rebulit,found to have rust and corrosion in bowls and nozzles,replaced fuel pump ,diaphram found to be leaking,motor seems to run on top two cyl.at low rpm ,has spark to all 4,pull lower plug wires ,no change.owner states NOW that he had to use starting fluid last time to start,fuel stabilizer bottles ALL over boat(I suspect he had a water problem)I'm using aux.tank.still hard starting,better since fuel pump but not right,changing on motor fuel filter and checking reeds.Any ideas?I thought the problem would clear up after cleaning carbs due to lower cyl.'s not working.
