I have a 1987 Classic 50 45 h.p. serial #0B113589 that I just took possession of and I have no idea of its history. It started right up but only ran for about 30 seconds before it stalled out with gas running out of both carbs. I disassembled both carbs and installed new gaskets and needle valves. (The valve seats do not appear to be replaceable.) I adjusted the floats from instructions obtained from Seloc online. The carbs are WMA6-3 (Top) and WMA6-1 (Bottom). Re-installed the carbs but the problem still exists.I have replaced the stator, trigger, switch box and rectifier and rebuilt the fuel pump prior to rebuilding the carbs. Its been suggested to me that the engine may be out of time. Is this possible? I have little to no experience with out board motors and Selocs instructions for timing a motor are confusing. Any ideas or suggestions? Any and all help would be greatly appreciated!

Not sure how timing and trigger, switch box and such would affect the carbs. It sounds like maybe the carb floats are soaked and not floating anymore for fuel to be coming out of them, flooding the engine and shutting down. I'd also check the fuel pump, filter and fuel lines all the way to the tank just to be sure they are good yet as well... But fuel coming out of both carbs points to a fuel delivery issue... Are you sure the chokes are working and not stuck? If the chokes are good, my guess is carbs again...
