I live in Canada and the temperature is starting to drop drastically. I have a 1975 B210 but it took me like 15 minutes to get it started yesterday. My father who lives in another part of Canada told me he had the choke turned all the way down. I now need to turn it back up. I am not a mechanic. Is this something I can do on my own, or do I need to take it to a garage? Thanks for the help in advance.
