Thanks for the update, I removed the previous post to avoid confusion.
By the way folks - the two 16mm long screws for the choke bracket are essential, if you use 14mm long screws in that position you can easily strip them out.
Tell that to the people who stripped out those two holes. Why not simplify things and use 14mm screws on the top too? Compared to the rest of the bike, this is hardly too complicated.That is simply not true with socket head screws on CVK carbs, unless one insists on using washers (which are not necessary anyhow); 14mm screws will make full thread contact with the bracket & no washers. No need to complicate things. It is OK to use 14mm screws all 'round. However, if one wishes to mix & max screw lengths, be my guest...
I read about that here on TRat, source of all knowledge. It's happened, although I'd guess that those riders were also over-tightening the screws.Which two people stripped carb bowl threads with 14mm socket heads & no washers?
