I know engines will run good on a white plug, and leaner mixes result in more power, but at the cost of internal parts. With all your mods, you might go beyond the 140, but I doubt it. If all else fails, pop the 140 in and see if you get color.

I was running it dry
I will oil it tonight. I want to make my internals last.

So even when you have the pedal WO, most of the time you are still running on the needle, not the main jet. Therefore, you are really never sure when you are running on the main jet.
I bet it will help, because most of the time we are running on the needle unless the engine is winding it out to the max.

Funny thing is my old carb the needle did not come through. By that I mean my new carb the long main needle comes all the way through to the the main jet sleeve.
I have another main jet sleeve ( needle jet) that has a smaller inner diameter and has more holes on the barrel. the plug tip is no longer getting that scorched white color on the metal tip, maybe I am just running off the needle.
I looked on my old carb and I didnt see how you would adjust the needle
And Johny I am cutting engine on WOT .
