Still will not run correctly. Had bad fuel w/water, that got run through a 2002 50 HP Yamaha that ran perfect always with NO problems. Took apart carbuerators and detailed cleaned all components, cleared all holes, lines, cleaned tank, everything is 100% clean. Installed external fuel filter separator. Motor seems to run great at higher rpm's but idles rough and bogs in attempts to accelerate form idle. I did not replace any components but meticulously cleaned everything in all 4 carbs. Fuel pump is clean and diaphragms are intact. What needs to be done. I did not adjust anything and was very careful during cleaning. Help me get back to fishing...I also replaced spark plugs with new ones.
