Just purchased a 1985 Sea King. It's a 15 horse, model #VWB52122 , serial# 58X3756. Not running. Soaking the carb tonight. Put in and gapped new plugs .030. Cleaned and set points .020. Sanded magnets on flywheel and heels of coils. Have some spark but wont run. I did manage to get a cough out of it this evening. Is Sierra 18-5009 the right tune up kit for this motor? Also wondering where a good place would be to get new coils if necessary. I'm hoping a good carb cleaning brings her to life. Hope I don't have a crankcase pressure issue. The cylinders both tested at 100 lbs. so I think I'm OK there.I don't have a carb rebuild kit and was wondering about a good source for that and which kit to get? It is a walbro LMB229 carb.
