I have a 1999 Honda 90 which has not been run since last fall (running fine) when it was run out of fuel and the bowls drained. Just changed the fuel connector on the engine to newer rectangular type and installed new fuel hose/lines. Started engine and it ran rough at idle and was getting fuel out of air box drain. Assumed I only had a stuck float as tapping the bowl cured the fuel issue. However still rough idle and rough at higher throttle. Removing plug wire from No. 2 cylinder gives no change of RPM. Plenty of spark so I'm assuming completely plugged jet. Is it possible to remove only one carb or does the whole assembly need to come off and all carbs cleaned/rebuilt.
