48IDA fuel level and float height.

[Eljaro]

I had an experience recently setting up 48IDA Webers on a 468 FE. I just took the setting and jets I had in my 482 FE and set the up on this engine.
All ran fine except the off idle was terrible and when cornering the engine would miss and stutter.
After trying all sorts of jet combinations I came to the conclusion the the float levels were incorrect.
Standard wisdom is that 5.5 to 6 mm for the float level above the carb deck is the correct adjustment.
Unfortunately carbs are inclined 10º and engine is not level but sits lower in the back,
Since the manual says that the fuel level inside the main well has to be less than 5-6mm below the nozzle bottom edge, in order to achieve that the float has to be set at 7.5mm above the carb deck.
So if you have the Weber setup with inward inclined carbs, 7.5mm is the correct float height.
