Also Mac, the fuel injector harnesses are butt-spliced, and tend to corrode and fail on these ol' ponies. We recommend that if anyone is having intermittent problems, or is doing an overhaul or top-end job, to open them up and give them a proper solder connection as a refit.

If they're leaking, an initial startup will be delayed, given the pressure has to build back up in the manifold. You're carbie-familiar with the leaky ol' AAP, but giving the dipstick a quick whiff will tell you if you've got fuel in the oil or not. It all goes to the bottom, carbie or EFI.
