Need Instructions for old OS 7M carb.
I picked up a clean OS 61 FSR ringed engine last year. I put in on the test stand and it ran very well. It has a 7M carb on it, however, and I have no clue as to how to set the low end on this type carb. It has two adjusting screws on the same side of the carb as the needle valve. No one at the local Hobby Shops or in my Clubs can remember what the two adjusting screws do. This carb was on some OS engines in the mid 80's. So if anyone has some info on this type carb, I would appreciate the help. Thanks in advance.
