i have a 92 model 25 merc it only runs on one cylinder when it can rev it up and seems to run on both but one cylinder is weaker than the other. ive checked the compression on the weak one and the spark and cleaned the carburator and put new plugs all looked good but still the same result.i put the compression gauge on it and it hits 120 on both cylinders. any ideas would be greatly appreciated
