My carbed 75 behaved the same way. You may want to ask the person that worked on it what he did with the carbs. My Honda mechanic told me my carbs were dirty. He said that the choke circuit on the Honda carbs has very fine jets that are prone to plugging. I hired him to remove and clean the four carbs. I've cold started it at least 30 times since the cleaning and it now starts cold in seconds every time. It runs great and I plan to keep fresh stabilized fuel in it at all times. His recommendation was not to drain the carbs for the winter. He told me to keep fresh stabilized fuel in the boat and pump the primer bulb a few times over the course of the winter to keep the bowls filled with fuel thus voiding the carbs of air to prevent corrosion. I'm also planning to install a remote fuel filter just for good measure from tank source contaminants.
