Whenever we rebuild Solex 40Pl carbs the screws that hold the Float Housings in place always seem to have been overtightened and damaged.



You can see that the screw has burred over and even with a good washer they don't tighten up well.

We have made some new screws in Stainless Steel and with a new washer pull the cover down more effectively.





I don't know if I should have them 'Yellow Zinc' plated or leave them alone.
