Yes it helps for setting the floats; thanks I am still trying to figure out how to remove and clean the idle jets. This is what mine have; what looks like a tamper proof head. I have noticed 4 very very small holes right where the butterfly valve touches the body, these are right above the idle jet location so pretty sure I have to get these out to get this all cleaned up.
Found that there are several tools for these: http://www.newbonneville.com/html/d_tool.html or https://www.amazon.com/dp/B003CMWC4U?psc=1&smid=A1TFBK3C7LO58P&ref_=chk_typ_imgToDp
I had to get the idle jets out with the special D tool in post 23. That and another good cleaning while on the bench. Now I just need to get 2 new bowl seals (T1241036) but they are still on back order from local dealer.
