Only several weeks left to the season in MA.....................1990 Johnson 120. Cannot get up to full throttle. VRO disconnected. Spark all around. 120-130 lbs compression all 4 cylinders. Same as always. Starts, idles, and runs low speed no problem. Cannot get up to full throttle. Feels loaded down. Had a batch of bad fuel (water mixed-in). All purged, new fuel filter and water seperator. All that's left is the carb. Could the bad fuel had caused carb problems. Any suggestions before I do a carb teardown? Can carb be rebuilt without touching the jets? Thanks in advance to all for your suggestions and directions.
