I recently rescued a 7.5hp Evinrude Fleetwin from a friends basement where it has been sitting for about 15 to 20 years since it has last been run. Obviously I have to go through the carb and lower unit before I try and start it. The model# is 4443-43412. The problem I am having is that I can't find anyone that list a carb kit for this old of a model. Even here at I boats they do not go back this far, I have called several on line reputable boating stores with no luck. Does anyone have any suggestions where I can look for a kit. This model also has the neutral clutch. Thanks.
