The shop manual says to disconnect the metal vac. line, but I doubt that everyone bothers to, as it is a pain. I cut out a section of line and replaced it with rubber tubing, so I could just apply a clamp to block vacuum and set initial timing.
Good luck setting Load-o-matic timing curve without a Sun machine & an accurate monometer. Adjusting the springs to allow earlier/performance advance results in too much total. Most people that want to maintain higher initial likely just tighten the springs a little at a time until the pinging stops. I fabricated a mechanical advance stop to maximize acceleration while limiting total to a safe #.

Hey guys,

I tried searching first for this and wasn't able to completely confirm and want to be 100% sure. On a loadomatic distributor (EBU 239 motor) do you still follow the typical ignition timing procedure of disconnecting the vacuum advance and plugging it to set initial timing? I want to be sure loadomatics aren't some goofy exception to that. What are you guys usually seeing or doing for total timing - most of what I'm seeing is about 36 BTDC @ 3600RPM? Thanks for any input!
