Title: ST.60 venturi..?
Post by: Lauri Malila on July 03, 2015, 12:02:21 PM

Hi.

What is a typical venturi (true venturi) size for ST .60?
No, I'm not going to use one, just helping out a friend.

Hi Lauri

depends on model and head  average  is .180 diameter (#15 drill)  but can use smaller or larger #13 to 17  drill... "if"  it is a venturie  and  not just a straight hole

Thanks, Randy.

It will be adjustable, with plug-in inserts. I just needed a starting point. L
