Hi. I have an HL 334a carburetor. do you have any ways to regulate? In the servis manual it is average for me. I have the setting L 45 ‘and H 30’. Setup on a stand. I haven’t driven yet, engine before run-in. I don’t have an EGT sesor. Do I only have to check the color of the spark plug and exhaust?
On the setting with the servis manual, black oil was running everywhere.
