12 dgrees before top dead center for a '68 - 69 era 400.
quadrajet carb but not sure what size it was. ANSWER: The DISTRIBUTOR was the same single point type used on all 1969 Pontiac V8s, except for the extremely rare optional "magnetic pulse" electronic distributors made. The timing curve and initial timing setting was varied for each engine application. The CARBURETOR was a 750cfm Quadrajet.
To set the timing marks on a 1969 Pontiac LeMans, first ensure the engine is at top dead center (TDC) on the compression stroke for the number one cylinder. Locate the timing tab on the timing cover and the harmonic balancer; the timing marks are usually indicated on the balancer. Align the mark on the harmonic balancer with the desired timing specification indicated on the timing tab. Adjust the distributor as necessary to achieve the correct timing setting.
To set the timing on a Toyota 22R engine find the distributor. The engine will have marks at which the distributor can be set. The OEM setting for a 22R engine is 5 degrees.
the timing shoujld be 8 degrees BTDC. If your engine has a vacume advance hose running to the distributor than you will have to remove it from the distributor and seal it off before setting the timing.
The distributor is set to 0 degrees with the aid of a scan tool. it can not be done with a timing light.The distributor is set to 0 degrees with the aid of a scan tool. it can not be done with a timing light.
Assuming that you know how to use a timing light to adjust timing: 1. Disconnect the electronic spark control at the distributor. 2. The timing should be 10 degrees btdc. Rotate the distributor to achieve the proper setting at the timing mark on the crankshaft.
If you are setting the timing with a timing light then it don't matter where the rotor is pointing. But if you are putting the Distributor in then yes. When it is in, It must be pointing to #1 on cap so vaccume advance don't hit the thermostat housing when you adjust the timing with a light.
The distributor is synched to zero degrees with a scan tool, it is not done with a timing light.
Timing is controlled by the computer and is not adjustable. The distributor, if equipped, is set to 0 degrees with the scan tool. This can not be done with a timing light.
Timing is the position of the distributor rotor in relation to the #1 spark plug wire lug on the distributor cap - when the #1 cylinder is at top dead center.
Oh, dude, setting the timing on a 1999 Honda Civic EX? That's like trying to explain quantum physics to a cat. Basically, you gotta locate the timing marks on the crankshaft pulley and the engine block, then use a timing light to adjust the distributor until they line up. But hey, if you're not into getting your hands dirty, just take it to a mechanic and let them deal with it.
To set the timing on a Toyota truck, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, check the timing marks on the crankshaft pulley and the timing cover to align them correctly. If necessary, loosen the distributor hold-down bolt and rotate the distributor until the timing light indicates the desired timing setting. Finally, tighten the distributor bolt and recheck the timing to ensure accuracy.
