Feeding Issues with 441 Clone (Ferdco Superbull 2500)

It could be binding on the bracket behind the roller.loosen both screws alittle & lift the foot up & see if it helps,the roller just need to be barely touching it.

I think you are referring to the area circled in blue, it actually doesn't seem that the wheel contacts it at all during its travel, but I loosened it some more.

When I take it apart again I am going to check on this slot circled in red because I don't believe this machine came adjusted to with the presser foot travelling very high, and this issue only seemed to appear when I tried balancing the feet.
So there may be something going on there and I never noticed it until I attempted to balance them.

Another cause can be tightening the ring on the pressure foot adjuster,it's best tio leave it loose it can't back itself out.I think once in a while the paint is high in one spot when you tighten the ring & will cause it to bind.

I loosened it and it still happens, I took it out completely and noticed that when it starts to jam, the top of the presser bar that sticks out tilts towards that balance wheel side of the machine.

All great advice, and I’m probably way off base with the next comment, but I thought I’d throw it out there. .  When I look at the picture  @Deek posted it reminds me of the linkage in a lever action rifle.  Keeping with that thought if you have to take the linkage out again I’d look at the hinge points and where’s movement, see if there is a rough spot or burr that might be catching.  It might be hard to see by eye, so get something soft like a dryer sheet or a Q-tip and run it across the surface, if there’s anything rough it’ll show up. 

At this point I am open to try anything to get this thing working, I'll check this tomorrow or Monday.

I can see you oiled the pressure bar,how about the part you circled in red & at the top of the bar?When it sticks before you do anything try to tighten or loosen the foot pressure adjuster once in a while they aren't drilled straight & you might find a spot where it'll work w/o jamming.

There doesn't seem to be a position for the pressure adjuster screw where it doesn't jam up, and it still jams without the screw.

When taking apart the machine again today, trying the method Tequila mentioned above, I didn't see any burrs.

I also slid the piece that moves through that slot up and down and met no resistance.

But I noticed the walking foot was meeting some resistance when sliding it up and down by hand so I removed the "upper feed bar guide" from the "frame driving base", oiled it and put it back together (names are according to my parts manual)
This reduced the resistance but when I put it all back together and timed and recalibrated, the problem still persists.

Did you do this with the pressure bar in it?Once in a while I've seen where you have to polish one side (of the block that sets in the slot)  like the slot wasn't milled correctly.

I will check this tomorrow morning.

I was told the mechanic at the company where I bought this should be back from vacation tomorrow as well, so I will give them a call and see if we can figure something out.

Machine is maybe 4-5 months old so it is still under the warranty.
