I assume your hanger and RD are straight / not bent?

Tuning the RD is pretty simple.
1. Shift the chain into the smallest cog (right shifter in highest gear)
2. Set your 'high' limit screw. You should be able to visually align the smallest cog on your cassette to your upper pulley on your RD, so your chain runs straight.
3. Reset your barrel adjuster on your RD to it's smallest / shortest setting
4. Reset the cable to your RD so that it is fully tensioned (don't need to use excessive force)
5. Now you can start tuning. Using the right shifter, shift to the next cog up. If it does not shift up, adjust the length on the barrel adjuster until it finally shifts to the next cog. Repeat process until you reach the last cog but typically the first barrel adjuster adjustment should allow proper shifting.
6. Once you get to the last cog on your cassette (biggest), you can set your 'lower' limit screw. Again the cog should align with your upper pulley of your RD.

Hope this helps
