Okay, watched the
CIS video on youtube last night and added some things to check and work on. Also got my
fuel gauge set from amazon, hopefully that's all good and can test accordingly.
Last night we tried a TSS from a running '75 911. Also tested the CDI, but the one from my '77 did not allow his 911 to start up, so not sure if there is an issue there or not, his battery was low as well. They look the same physically, but may not be the same inside. WUR is different, so couldn't give that a go.
Up next checklist:
•check WUR for power
•check AAV for power (both seem easy enough)
•test basic system pressure
•try basic DIY airbox test
•replace fuel filter (pelican order showed up)
•trace/replace some vacuum line (pelican order showed up)
