i have a 1990 225hp yamaha v6, when i pull the spark plug wires off of the top two cylinders the engine doesnt change its sound so im assuming they are dead (powerless) cylinders. i have cleaned the carbs, replaced spark pluggs, hooked up fresh fuel, its getting spark to the plugs, they have good compressing 110 on each... what else could it be??
