Inclined carb. Change float level?
I converted my car to a rotary engine. The 12A engine is mounted level in my car. As the position of the original carb is mounted at an angle to the engine, the carb is not level. It is about 5,5 degrees inclined.
Now i am struggling with a lack of power on the secondairies. And i think i gonna blame the float level. I made a drawing of it:
The upper drawing shows the two float needle valves and the float level.
The lower drawing shows what happens if the carb is at an angle. The red lines shows the actual float level. If i use the centre of the barrels as a refence point, the pink lines shows how the level needs to be adjusted to get the correct level at the reference points. So the left floatlevel needs to be 4.2 mm higher and the right level needs to be 4.2 mm lower.
I choose the centre of the barrels as reference points because thats where the mixture comes out.
How does this theory sounds? Did i pick the right reference points? Can an inclined carb cause lack of power in the secundairies?

you seem to have it right in theory. is there no way to level it? i would try my best to level it. i wonder how much it is going to affect the sloshing of fuel when going through a corner.
