1976 Johnson 75 HP Carb Jets

[PAMeyer]

Hi, I am installing a set of Boyensen Reeds in my 1976 Johnson 75 HP 3-cylinder outboard. I have read that I should change the low-speed jets when doing this. 1) It appears to me that these are fuel, not air, jets, so I should install a larger size, correct? The factory service manual indicates the low speed jets are #317474 (.027 inch). The Boyensen istallation instructions indicate I should increase the size to .029 inch. Does this sound right? 2) Where can I purchase replacement jets - I've looked on iboats.com but haven't found them. Can anyone suggest another location?
Thanks for your help.
Paul

Thanks for the quick reply, but I just removed one of the low speed jets and it's a #32, not #27 as the factory manual say it should be. Should I reuse these jets after installing the Boyensen reeds, or increase them to #34?
Thanks,
Paul
