Reply To: Tillotson Carb Brass Plugs

[Buccaneer]

Frank, I believe the small end of the plug was about .470, and the
round head end, .500. Therefore, it probably doesn’t qualify as
a 7/16″ (.4375) x 20 thread.
I gas the round stock a 3 degree taper before I started turning it,
making it close to the taper on the original plug.
I got to thinking last night that I should look in the Machinist Handbook,
to see if there’s a listing of special brass fittings. It’s out in the garage,
and I’m on my way to the dentist in a bit. 🙁
Thanks.
