    The drill bits are numbered drill bit sizes. They come in handy for verifying orifice size and cleaning out orifices. You can get very tiny sizes to clean pilot burner orifices.
    Your link did not work, so I have taken the liberty of fixing it.

    It is essntially the same as what I said in my post to a simular set of numbered drills , but mine are available in this side of the pond.

    Great minds think alike

I pulled out my handy drill index to check the piston and sure enough the orifice was too small. It was the correct piston but somehow copper had deposited itself in the piston orifice. I used my drill and chipped out the copper and put the piston back in and it worked great after that.
    You really need to measure the piston orifice to make sure copper hasn't reduced the orifice size through some type of electrolysis. You'll need a drill index that measures orifice sizes.
    That's very interesting, I wouldn't have considered that.....
