Hey guys. I hate a beat a dead horse but I'm still playing hell trying to get my 108 Timed correctly. Here's what I've done:

Valve Adjustment - Improved performance and idle 10 fold. WOW!
Compression check - 137-147 psi. Looks about right for an older M130

Timing has been set @ 6ADTC on idle w/ the vacuum line attached and still runs like crap. I want to make sure I'm reading the timing mark correctly After vs before TDC.

Also, I picked up a cheap tach that'll give me readings @ 4500rpm's. There has to be something I'm missing here. Any help is appreciated.
