perhaps crank pulley has slipped from original position
Stick with the coil recommended by Mallory.
That requires a timing light, you loosen a bolt on the distributor and turn it a little until the marks on the main pulley match a notch that you aim the timing light at.
TDC, top dead center is when the number 1 piston is at the top of the cylinder. 8 degrees before TDC is where you set the distributor so that is when the spark plug fires. You use a timing light to set the distributor. There is a timing mark on the crankshaft pulley and a series of marks on the timing chain cover that will show where 8 degrees before is at. The timing mark on the pulley is a small notch in the edge of the pulley closest to the timing cover.
The Chevy Cavalier 2.2 liter engine timing marks can be found on the main pulley. The timing marks will be scattered around the outside of the pulley.
Use a timing light and turning the distributor. Timing marks (numbers) are in the crankshaft pulley area and the line is on the balancer (next to pulley). Make sure you disconnect the vacumm line to the advance on the distributor while timing and plug the hose while timing. 4BTDC auto trany, TDC standard trany. If the motor is old & worn you can leave the distributor slightly loose & go for a drive and time it manually (with advance hooked up & up to operation temp) to where it won't ping on acceleration and has decent performance.
you turn the distributor and use a timing light
No need to if the distributor was not moved.
same as a 350
turn the distributor
SORRY, But it don't have a timing belt. It has timing chain and gears.
how do you set the timing on a distriubtor for a 2002 Chevy blazer
You can monitor distributor degrees with a timing light.
