Yamaha 2 stroke 150 - need to know carb settings for pilot screw

[yama8454]

I have a yamaha 150 txr engine. The carb is stamped as follows:
64C10 S 621400 F 61 p 8326

What type carburator is this?
An A type, C type, S type, L type, P type or D type.

The yamaha spec says, the counter clockwise turns are based on the carb type. If I know the carb type, I can tell how many out turns I need to make on the pilot screw. I have the yamaha book, but am unsure of the number of turns to make when I counter screw the pilot screw.

I had different settings for port and stb sides on my 200's. Better check the book.

[yama8454]

book says its based upon carb type, example A, C, S, L, P or D. If carb type is P or D then port and stb settings ARE different. I don't know how to tell the type carb (a, C, S,L, P or D) , do you know Tuck?

Carb type stamped on top of carb to the left so w a 64c10 stamp that means it's a type c
