1975 Honda CB550 K1, all stock engine (air box, carbs, etc, all stock)
Here are my symptoms:
- The colder the air, the harder to start and the more cranking it takes - won't start at all when colder than about 60degrees outside - starts fine after engine is warmed up.
- The warmer the air, the smoother it runs throughout the power band
- Runs very rough when cold - the colder, the rougher
- Choke on makes the RPM drop rather than rise
- Smells like it's running rich, but air/fuel mix screws are set as specified in manual
I'm just curious as to what these symptoms point to. I suspect it could be one or more of the following: vacuum leak somewhere, running rich, carbs out of sync. Let me know if any or all of these are valid or if there's something else it could be
Thanks!
