Question about 1977 BMW R 75-7
I just reclaimed my 1977 R75/7 from my usually very astute brother in law, given to him when I went on deployment 5 years ago. I visited him last weekend and noticed that he had kept it outside during this time and I asked if I could take it back home to restore it. I asked when the last ride was ('early last year') and if he had put in stabilizer in the gas (No!) When I pulled the carbs (64/32/13 Bing), I opened the float bowls and found the right side bowl packed with a dense white powder, with minute streaks of red. I have never seen this in carbs and thought the red was from rust, but am confused with the white powder. The left bowl was less severe and took much left effort to clean. I cleaned all parts visible with the bowl removed and flushed thorouly with carb cleaner. As always, when I reassembled the last carb, a spring (1/2 in X 3/16, 7 coils) mysteriously appeared. I did not notice this spring in the first carb, even though I performed the same cleaning as with the first. Did this spring spring from the carb, or is this a part that entered the lost part time warp and is just now returning from its trip?
Thanks Tom King
Tom, you can see the parts microfiche for the whole bike here. I see five springs, one listed in the "cover carburetor" and four in the carburetor-choke body". Do any of them look familiar?
