High speed Orifice Plug 328544 size?

[oldfarmall]

Hello-

Does anyone out there have specs on the diameter of a high speed orifice plug with OMC part# 328544 (63D)? I searched the forum and only found 1 thread with info,
.044? Is 63D supposed to be .044 or .063? Thanks for your help in advance!

The number indicates the size. #63 means .063". The D indicates a unique feature, such as the shape of the hole.

"D" actually indicates the direction of flow of fuel through the hole, which is head of jet to base. "C" indicates flow is from base to head.

Jet number indicates orifice diameter in thousandths of an inch.
