I have never seen a fan wobble that the kit wouldn't cure. I use the temporary weight, the rubber clip that comes with the kit. The weight has the most impact when placed at the outer edge of the blade. Just start with any blade, turn the fan on to see if the wobble improves. Check each blade, in turn, to see where you have the most improvement. The fine tuning is done by moving the weight toward the center until you find the spot that is wobble-free. Then replace the temporary weight with the adhesive backed lead weights. It may take more than one weight.
