[Spridgets] Air pump ports

[Larry Daniels]

Actually, Bud, where it came from is from personal experience of plugging 3 
different B-series heads with exactly 7/16 - 20 X 1/2 hex-head plugs. 
Before my post I double checked my memory by going out to the garage and 
looking at the bag from Fastenal that contains the remainder of the ones I 
bought.

Now, I cannot report from personal experience on the A-Series, but the 
B-Series is most definitely 7/16-20.

If you still think I'm wrong, try a B-Series and report back.

Nope.  The B series head uses the same size as the A series.
Dunno where the idea of 7/16 x 20 came from.  7/16" is a pretty damn big
hole, actually.  FAR too large for an air injection nozzle on a
small-bore engine like an A or B series.

Yeah, the 7/16 - 20 X 1/2 is for the B-series head.

The ports on my head are 1/8 x 27 NPT.  Allen head plugs are available
at
your friendly local ACE hardware.
