What should timing be set at?
Timing specs vary, but a good rule of thumb is to set the timing at 12 degrees advance once the engine has started up for the first time.
What should the timing be on a 350?
The timing can vary between 2 and 12 degrees BTDC, the recommended spark plugs are different and even the plug gaps vary. In most cases starting out with 12 degrees of initial advance is about right.
What adjusts the ignition timing?
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you’ll advance the timing by rotating the distributor counterclockwise, and vice versa.
What should my timing advance be at idle?
All discussion of ignition timing starts with the initial timing. This is the amount of advance at idle with the spark triggered Before Top Dead Center (BTDC). Most stock street engines call for 6 to 8 degrees of initial advance, but this is not set in stone.
What should the timing be on a corvette?
The stock setting is 6 degrees Before Top Dead Center (BTDC). Each little line on the timing tab should equate to 2 degrees. If the timing needs adjustment, I walk to the passenger side of the engine and loosen the bolt that secures the distributor to the intake manifold (you have to access it from the passenger side).
How do you set ignition advance on a corvette?
Most guys mark those spots (ZERO on the tab and TDC on the damper) with something that will make them stand out when the timing light is flashed at it. I use red fingernail polish, others use whiteout, etc. The ignition advance is determined by where the groove in the damper aligns with the little hash mark on the timing tab.
What kind of engine does a 1972 Corvette have?
Notes: Base Corvette Coupe with 350 cu. in. 200 hp engine and wide ratio four speed manual transmission: $5,533.00. Base Corvette Convertible with 350 cu. in. 200 hp engine and wide ratio four speed manual transmission: $5,296.00.
Where does the vacuum pickup go on a corvette?
One of these band-aids was “ported spark”, which moved the vacuum pickup orifice in the carburetor venturi from below the throttle plate (where it was exposed to full manifold vacuum at idle) to above the throttle plate, where it saw no manifold vacuum at all at idle.
