Mid-Suffolk CB500 Update & Parts Enquiry
Roxy John:
Morning all, just another thought on the annoying hanging idle - when I dismantled the carbs, the air/fuel mixture screws were between 1.75 & 2 turns out. When I rebuilt, I installed all screws to 1 turn out as per factory spec. I've been having a read on t'internet and fancy having a play with these screws before stripping everything down again, however, I'm not sure what would be the best procedure to adopt when adjusting - do I set idle to 1000ish and then turn screws in/out and see what happens? Or set to 2000ish and do the same?
I've got the vacuum balancing gauges so can ensure all in sync but I'm not experienced with setting up carbs and don't want fiddling with one thing to cause more problems than I already have! Any advice appreciated.
Nurse Julie:
The 'pilot jets' you are refereing to, I'm assuming you mean air/ fuel mixture screws on the outside of the carbs?

Yes Julie, those are the ones I meant - I've revised the wording so it makes sense!
(Thank you for the o-rings and the note :D )
