Is there any correlation to the size of the pilot jet and how much fuel gets through the starting circuit/choke?If a bigger pilot was installed would it also allow more fuel through the choke circuit?
Ah, hang on a second. The enrichment circuit (for starting) has it's own pick up tube in the float bowl, controlled by a cable (with a rack system for multiple carbs) and a needle and seat plunger. The pilot circuit is on it's own with a separate path and jet.
