Hi all,
Today I did a little carb tuning. Needed to hear the engine roar
When I plug my vacuum gauge, the needle is shaking, between 16 and 20 Hg/in.
Ignition timing is set correctly. It's a bone stock 350, never rebuilt I guess. Just have 2,5" exhaust, new intake and 600cfm Holley.
What does it means ? Valve problem ?
