M2c cylinders

[NW Mailing List]

Most of the Y class engines had them too, but they are less noticible, since 
there is no "bulge." The bulge on the M2's results from the fact that it is a 
retrofit, and they didn't all have it.    Jim Nichols

"Can anyone identify the bulge on the right side of the cylinder block--between 
the valve and the cylinder on the M2 or M2c?"
 
I think you are speaking of the "By Pass Valves". These were used when drifting 
and are automatic in operation. they permit free circulation of air from one end 
of the cylinder to the other.
