Thanks, Rule! I was a little confused about whether to drill THAT part of the "tube" as the restriction, or the bottom end of the tube, or both. Let me look at page 106 again.
OK, here's a question for you. I wrote this down in my notes from the bible as recommended sizes for "recipe 2":
"Secondary Tube restriction: .036
Main Well Bleed Tube: .036"
Those tubes that hook up to the little holes in the top of the airhorn are the "secondary tubes" in my notes. They currently measure .024 at the BOTTOM.
Should I drill them out to .036 at the bottom of the tube AND at the top of the air horn?
Thanks in advance.
