I've not seen good results from rebuilt injectors. My impression is 
that they don't always meter out the correct amount of fuel. New or 
used bosch 007s are what you want. Keep in mind that if the plug is 
fouling, the problem may not be too much gas, it may be too little 
compression or too much oil leaking past the rings.

I also install the seal on the nose of the injector first. Then you 
have to make sure that it seats nicely in the manifold when you 
install it.

??? You're the one who reported finding it. You tell us.
