I adjusted the fuel injection pump. Was pretty straight forward like you stated, except for the bolt on the bottom right (when looking down at the engine from the front) is a really pain to get to and actually turn. Tried every type of a wrench and socket I had, just not much room to move the wrench and sockets didn't have room to actually go on. In any case, will report back once I get the dash put back together and actually drive the truck. The timing marks were aligned directly up instead of being advanced a bit.I think most people on here believe the easiest way is adjust and test drive until you get the best performance under all load conditions while road testing. Facing the engine from the front looking down on the injection pump move the mark on the pump to the right of the blocks witness mark to advance the timing. Generally on a well performing pump and engine lining up the witness marks will put you in the right place The thickness of one witness line on the pump to the right of the block line will be all that is necessary in some instances . Trial and err.
I figured out that this was my doing.
