At times one needs to fine tune the adjustments on the CNG system.
We all know it is just a pressure regulator under the bonnet with a bypass probably in the third stage to allow for idle etc.
I never had a closer look at the thing but I expect to find just two adjustible screws, one for the setting of pressure and the other for idle speed adjustment.
BEFORE I VENTURE into it, I would please like to know if someone here actually has the experience of adgusting the Italian CNG kit. PLEASE tell us in details how to do it
