Hello Honda fans, I’m a long time rider and Honda owner (as well as BMW). I’m currently working on a 1980 CB650 Custom bike. 32,000 km, came to me in pieces, a non runner with no history. After a lot of tinkering I have it running ok, and am trying to improve the infamous hard starting when cold. In my research the accelerator pump has been mentioned. In examining my pump I see that it doesn’t really operate. I believe the culprit to be the top spring. It was missing but I found one with the carb parts and thought it was correct. But it can’t overcome the spring behind the pump diaphragm at the carb bowl. Any thoughts to correct this? Any insight as to what kind of stronger spring I could find to use?
Second issue is the choke cable seems a bit too long for the choke linkage. I’ve seen some carbs have a plastic bit at the linkage, I wonder if I’m missing that. Or something else? I’ll try to post photos too.
