the engine feels like it only throttles up to half throttle. it starts instantly and runs good enough without backfiring or stuttering. I have 2 dead cylinders that get spark (maybe weak spark?) I know this because they shocked the f'ing s out of me while I was performing the "pull one plug at a time" test. I pull the plugs and the 2 bad ones are oily/gassy. I put a new plug in and it got oily/gassy. I pulled the carbs inspected / drained them, they had a bit of water in them. my question is can the plugs still be getting wet with fuel/oil if the carb is still dirty? what else might cause dead cylinders"
