If it didnt have points new, I dont think the provisions are there for them, probably ust be a flat solid section of block.
This is a K181, little smaller, same points.
Outer 2 holes are for the cover, inner 2 are for the points, the one in the center is for the plunger. If the hole is open, oil comes out..so either your hole was never drilled or there is a plug, id say no hole is more likely.
