OK, all you guys that are running a lean burn engine. When you go into lean burn do you have to give it more throttle as in a loss of power type feel?

I had my engine up to 23:1 A/F but notice its wanting to lay over at this level.

At 19:1 to 20:1 its fine but as soon as I go to 21:1 or over the engine requires more throttle. Plus I tried moving the timing all around and it didn't make a difference.

I'm starting to think I just hit the lean burn wall with this combination.

I'm going to do some more testing tomorrow because the weather is suppose to be a lot cooler and maybe that will help.
