G07 Shifted 25% left. Center jumpers not enough. What now?

I have a G07 that I just hooked up for the first time. I can get a stable image with good color so haven't replaced any components yet.

The image is shifted about 25% to the left. If I move the center jumper the screen does move a bit but the image is shifted way to much for it to even make a difference.

The H pot will move it just a hair but then the image becomes garbage. Any idea what I need to do here? This doesn't seem like a simple cap kit fix and the jumper seems to move the image a bit so that circuitry seems to be working.

It's hooked up to one of JROK's boards via a harness from arcadeshop so I am reasonably sure the wiring and board are solid.
 
Sounds like a possible sync issue. If you get a chance show us pictures of you screen and the 6 and 3 pin molex that attach to the monitor.

The harness is setup with one six pin molex fully populated with wires. There isn't a three pin. Is that my issue here? I can post pictures if needed.

So, I pulled the two sync wires out of the six pin molex and put them into a three pin and connected it to the two on the left side behind the six pin connector. The image is centered now but the top of the screen is bent and I can't seem to adjust it out. Any ideas? Seems like I'm on the right track just not quite there yet.

The h-freq pot should help. I don't recall if you said this is rebuilt?
 
Do a cap kit. Most cap kits include the curl mod. If it has an original flyback you may want to replace it also.

What's the difference between CBO and FBO? I can't find anythong on my chassis that indicates which version and I am seeing these two different types listed when looking for G07 cap kits.
