I am laying awake again with this one. Can the fuel pump push rod fall into the recesses, or is it long enough to actually start into its bore from the outside of the block. Assume the latter. Have purchased a new rod to go with the Carter pump. And, have not heard anyone talk about rotating the engine to get the eccentric back to allow no fight with the fitup. And, I am noting in the many threads on the subject that the inner bolt is a bear. So what my nitemares have decided is to use a stud on the outside to align as it goes in, with the inner bolt in place with socket and extension to get it started. But, am thinking that this is just another thing to keep me up at nite.
