Weber float level
 

I've just got my Webers restored. I've not managed to tune them in yet. I've fitted new "needle valves" and since the "shims" din't came with the repair kit, I've just used thin cobber ones I found laying around in my tool boxes. I wasn't aware of the importance of fuel level and so one, I'm completely new at this.

I have purchased a syncmeter and a fuel level gauge here from Pelican, after searching the forum a bit.

Today I used the fuel level gauge and checked the float. The floats was just slightly above or at the upper of the two markings for the Webers. I tested first without the engine running and then when the engine running, the readings was the same either way.

My question: With the fuel level just above the upper mark and not between the two marks, is that OK, or should I bother the shims it to stay between the two marks?
