Power Bar Returns on downstroke

My powder bar returns abruptly on the downstroke. Don't know what is causing this. Can somebody help me please. Is the old powder measure system.

Not sure how this can happen. The case pushing up on the powder funnel cams the powder bar over on the down stroke. Be sure the bellcrank cube is not slipping out of the notch in the powder bar. You might also remove the bellcrank and look for a crack in the housing where the bolt threads into it.

RE: Power Bar Returns on downstroke

The same thing started happening to me today on my 20 year old SDB. The culprit turned out to be square plastic bushing (Bellcrank Cube #13871) that is in the slot on the back side of the powder bar. The hole in the center of the Cube had worn to the point that one side cracked and was hanging the power bar's return.
