Do as Farmall says put the weights above the clip that is above the float.

SO starting from bottom it would be clip float clip weight and if you have it another clip. I do not have the top clip, neither one of my benders did so I am not sure if they are supposed to be there or not. It seems to work good with out it so I think it is there just to keep the weights in that one location.

The pic that Farmall mentioned is how I thought it was to be set up and after I got a good run of sap I had some pulsing of the float and rod and it just so happened that Farmall seen what I did in the pic and mentioed to me that the weights are to be above the clip and long story short I moved it and I beleive it works better, less pulsing right after dumping.
