turned this up for me on his lathe
he's no boy (nearly eighty years)
and finally fitted today when I sourced some screws from
stig fasteners who stock the correct size in various head types
I finally found out the thread size is 8.32 UNC
The carb saga is getting boring
fitted .28 Intermediate again and .68 Main
Hard to start still
Will not start cold with enrichener
Will not start hot easily, fires but does not catch and run.
This is not why I dumped my points and my old carb.
I will have to try with my old carb if I can get that not to flood etc.
