Mixture screw spring CB550K3
« on: September 29, 2025, 08:27:05 PM »
Does anyone have a spare mixture screw spring I could buy pls?
Carbs are PD46A and I’m currently overhauling. Took the 4 mixture screws out, and one of the springs is in two pieces. All the other parts seem OK other than the O rings which I’ll renew.
Many thanks
Harold

Harold - I was just about to list these on eBay as a spares set for £60. Probably more than you want to spend, but might be a good option as a spares resource - you could re-plate/replace all of the hardware over time and swap in/out on your set. Happy to do them for £50 to a forum member. The bodies are probably too corroded to be salvegable.

Hi James. Many thanks for the offer, but as it’s just the one spring I need, I will decline.
Good luck with the sale.
