The Master Cylinder	Posted 12 Years Ago
Supercharged Group: Forum Members Last Active: 4 Years Ago Posts: 974, Visits: 6.2K	This morning I was working on the ol' Y and decided to check the timing while there. Disconnected the vacuum line and put the light to it. Timing was @ ~20° advanced. Brought it down to 10° and it almost stalled. Didn't like it at all. Hmmm Checked the damper, it was spot on. Then I connected my vacuum gauge and timed it using just the readings on the gauge. Runs/starts good. Rechecked with light and it's back up to 16-18° advanced. Didn't notice any detonation or over heating (tho my electric fan did come on while I was leaning over it. 'Bout scared me to death). Runs good so I left it but it's got me puzzled. Any ideas why it likes the timing so far advanced? "The Master Cylinder" Enjoying life at the beach in SOCAL
