well tonight I took it out after putting smallest weight on, I feel stupid for even bothering with it after what you all are telling me, but it's acting just as it did without any weights. I don't know what to think of it. And figuring in a detonation issue I'm having, I put 4 gal of turbo blue into my tank which already contains 93 and it still detonates. I'm becoming very unhappy with this engine.
