I had a 4.5 hp Ted Williams outboard (Tecumseh powerhead). I use this as a kicker for my 16ft center console. My problem is that I have ran this motor quite a few times with no problem, however the last time I tried to pull-start it the I couldn't pull the cord. At first I thought the engine was seized, but after taking it apart, the engine and prop are free. So I put it all back together and once again tried to pull the cord, but the cord only pulls about 6 inches and then seizes. I can still spin the prop and flywheel by hand, but not with the same ease as I could when I took it apart. Any help would be great. Thanks
