Default Float Heigh Question

I adjusted my float height today after messing it up my first time. I found that the float height was at 10mm instead of the suggested 12.5-13.5mm. So, would this have caused my bike to foul plugs and use gas at a pretty fast rate? I am asking this because I read the following statement.

"If the engine has a "wet" rhythmic, soggy area at full throttle / 3k-4k rpm, that gets worse as the engine heats up, lower the fuel level by resetting the float height 1mm greater (if the original was 13mm - go to 14mm). This will lower the fuel level, making full throttle / 2k-3k rpm leaner.
If the engine is "dry" and flat between 2k to 3k rpm, raise the fuel level.
Example: change float height from 15mm to 14mm to richen up that area."

What vehicle was this referring to because WOT at 3-4000 rpms seems like a very low running V8 Big Block. But the idea of the top end drawing to much gas when WOT or the lowend not getting enough if jet correctly for the conditions that would be correct.

As far as fouling or consumption that would be the jets themselves.

I cant speak to the rpm situation you are reading from, but a high float level will definitely affect your overall jetting. You get the most affect from throttle off coasting or downhill situation.

If you have a reason for running a high float level, you can jet for it. Pros probably don't have the same level from one to the other. The difference in the way they do it is that they know WHAT that LEVEL is, and they work from a different base than we might. That saves guessing later when situations change.
