CB750 / Adjusting air screws makes no difference
« on: March 24, 2010, 09:31:00 PM »
Hi all,
Now the CB750 is back on the road, I'm trying to fine tune it. After a good ride out to get it nicely warmed up, I attempted to adjust the air/fuel mixture screws on the carbs. Currently their all 3/4 of a turn out, but adjusting them is making no difference at all!. My understanding is I need to adjust them until the engine idle speed increases then turn back the idle speed with the main adjuster.
Any ideas why adjusting the mixture screws is making no difference?
Best regards,
Paul
