An open bleed would need a lot of idle feed restriction and limit the time the transition circuit was active. You might get it to work, just might make tuning it a bit harder.
I can use a drill set to determine sizes, I 'think' the outboard ones have a reduced step down inside > but isn't that std for a brass insert to sit on?
"intersecting passage" I'll have to put it under my ole Science class microscope for that one. lol
I'll pull the carb again > it should have sippers vs bolts for as many times I've been in it LOL
Purchased the carb back in 98 from a friend that used it on his Hot Rod strip car > the inside was a mess until I went through it. It sat clean and bagged for a loooong time.
Dellorto DHLA 40's I know like the back of my hand, Hollies well, I know where the idle mixture screws are and know how to rebuild them.
Thanks again, Ray
