Good evening, I have a quick question I notice the feeder on my keystoker is pushing coal crooked/ unevenly l. I cleaned the hopper out and watched the feed push uneven. I cleaned any debris around but still doing it. Any suggestions is greatly appreciated thank you

How is the surface of your burner grates? If pitted or corroded, they can cause issues with feeding.

How about the nylon screws on each side of the pusher bar? Are they in good shape? If not, the pusher bar can bind up leading to feeding issues...

Grates are fine I believe it's the nylon screw I found a piece of the top of the screw between the slide and bracket.

I found 10-24 nylon screws at my local Lowe's... But if you're near Schuylkill Haven you could stop by the Keystoker factory for a set.

take pusher plate out and make sure the nylon screws and Nylon cam are in good shape and centered in slot. replace if needed. Also, Make sure grate is sealed properly in back , otherwise it it will leak and burn back too far on grate and possibly melt the cam and/or nylon screws. Also, too much draft can be drawn down thru hopper and burn back too far. Make sure you have draft gauge and stove / exhaust set up properly.
