I used a similarly modified COS for years. I found that I had to burn chunks rather than splits to keep the temp from running away from me. Generally I used chunks that were fist size or a little larger. Of course that means tending the fire quite a bit.

Don't be afraid to adjust the air intake if necessary. Most COSs are leaky enough that you aren't going to totally choke the fire even if you shut the air intake all the way. But I would leave the exhaust stack fully open unless you have to close it for a short period of time to tame a runaway fire.

Get comfortable with the fact that you aren't going to be able to maintain a completely steady temperature. I had to adjust the air intake almost constantly, and I was happy if I kept it between 220 and 270. You can still make good Q that way, it's just going to take a very hands-on approach. Eventually I got tired of it and switched to a WSM.
