Purpose of orifice in 1-2 accumulator housing

[PaulRV6]

My old Art Carr shift kit had me install an orifice in the housing (maybe 1/16") hole. What is the purpose of this orifice? I am using the stock GN SERVO but don't know if this has anything to do with it. Does the servo have anything to do with the accumulator circuit?
I'm just wondering what to do if I put a different kit in it. Thanks

The orifice restricts the oil going to the accumulator to firm up the 1-2 shift. Depending on what shift kit you are going to put in you may have to remove it. The easiest way to remove it is open it up with a drill bit.
