know has a negative effect on power as you get higher.

What are you doing for mixture control?

Some use a MacNeilly leaning block and at least one individual chose
to fly his without any provision for leaning.

I have the leaning block and during my original attempts to start the
engine, converted the carb back to original specs in order to
eliminate that (carburetion) as a problem.

Now that the engine is running, I'll be putting the leaning block back
on because all testing will have to be done with the engine in it's
flying condition.

With the leaning block, which is added on to the carb float chamber on
top of the valve body, you can run at full rich, or lean it to full
lean which kills the engine. Just like the carbs in any standard type
aviation carburetor.
