I took an OS 60B carb from an OS61WC engine and puted it in an OS91SXH engine, it worked good in my Freya. I've now have the same engine in my Acrobat but I lost the needle settings. I have problem to tune the low and the midium needles. Can some one tell me what are the factory start seetings for the low and midium needles or what needle settings are working good for him using the 60B carb. Please tell me the settings of all the 3 needles.
I use a model-technic 30% fuel, OS#8 plug.
Have a nice day :)
