I'm new this whole z and working on cars in general I have a 1982 n/a that is very close to running. The engine was rebuilt (I have no clue how well), but it cranks it had been sitting for 2 years after the rebuild due to ignition problems which got fixed. The engine I'm sure is tight, which is causing me problems. all the sparkplugs and wires are new, I drained all the old gas and put new gas in. I know it is getting gas and spark, but it still won't start, doesn't act like the spark is getting to the fuel as it is only occasionally firing. So I need to figure out how to get it timed well enough that I can borrow a timing light and time it officially.
Any advice of any kind on why this car doesn't run or things I should look at would be really helpful. Also I bought a new battery, so it isn't that.

okay depends how much work you want to do....reallistically you should pull the front cover off, take the chain off and time it but if you just want to check it you can try this.

okay to check time it you need to time it you need to set the crank to TDC (top dead center) you can do so by the marker on the front cover by the crank dampner. The dampner has a mark on it. just line that mark up with 0 and then head to the valve cover. Looking at the camsproket on the collar there is i little line punched into it on the sprocket there are grooves and they correspond to the 3 numbers on the sprocket. look to see which hole the sprocket is set on by looking for the pin in the inner set of wholes. once you find out which one then check to see that the line punched matchs the corresponding groove exactly. Remember the crank has a 2:1 ration on the cam...meaning you have to turn the crank twice to get the cam around once so if it doesnt line up the first time turn the crank around again. remove the plugs it helps alot when trying to turn these engines over. good luck. you might want to get ahold of some literature for retiming it.

Real easy. Pull #1 spark plug out put your finger in the hole have someone else tap the engine over untill you feel the air pushing out. this will be real noticable. Then look at your timing marks untill they are at TDC. Now look at your rotor under the dist. cap. Make sure it points to the # tower or before. If your there it will start. If its not stating there is another problem

Ok, here's what I would do. First set the engine rotation to the place where the timing should be, ie. if you should be at 17 degrees before tdc, use the timing marks to make sure it's at that position. Now you need to connect an ohm meter across your points. Twist the distributer until the ohm meter just shows that the points are making contact, no further. You should start with the distributer at the full advanced position and turn clockwise 'till they touch. Also make sure the rotor is pointed towards the #1 plug.
