My Addams that i recently restored plays great the only problem i have is that the swamp kicker only just returns the ball should i be looking at replacing the coil or would it be a plunger problem ?????????????

Thanks

Coils tend to work or not work, unless overheated and the centre deformed. Remove the coil and try removing the sleeve. If the sleeve comes out easily the coil is probably ok. Add new sleeve and reinstall coil. If problem continues (and coil is correct rating to start with so check while in there) it might be that plunger or stop has magnetized slightly and need replacing.
