Hello everyone, and thank you for all the information provided here. I have a 1961 Gale Sea King 15hp "GG18737" ( with no A,B,C,D after model number). The motor runs good. Looking under the hood it looks like the previous owner has done some maintenance over the years. The high and low speed adjustments didn't make a difference when turned, and the motor is hard to start at times. Compression and spark are good, using 24:1 fuel mix. I assume there may be a carburetor issue. I have a manual but no part numbers. Do I need to pull all my parts and match them up or is there a part # for a carburetor kit, impeller kit, and a 9" diameter x 10" pitch propeller (edges are chipped bad)? Not much help from the local marine repair guys. There telling me they need to tear it apart to find out what parts are in it, "For a fee of course". I want to do my own work on this motor. Any thoughts or suggestions before I start this project are appreciated. Thank you in advance for any help.
