So I disassembled carbs on 82 CB750 that idled only on choke and killed with throttle.
I'm sure I did not do the process justice. They looked pretty clean. Removed all the jets ... they all looked clean. Stuffed the wire brushed through each including the pilot jets, at least the various holes on the underlying jet. The main hole pilot jet hole was too small for the carb set of brushes/files I had (amazon) but the hole was visible.
Inspected pilot jet operation while running and with throttle there is virtually nothing squirting out of any of the pilot jets.
Is there an issue with the accelerator pump? Are the jets not clean just because I can see opening though the entire jet?
Any thoughts?
I'm also getting a bit of white smoke once at temp out of cylinder 4. Somebody tell me that is something other than internal ring or valve. :-(
