i think i have a timing issue. with the crank pulley at TDC the rotor should be at this point correct?

i have the firing order correct. its 1-3-4-2 on a kae i have spark and fuel and i think my timing is messed up.

this is the cap it only goes on one way so i didnt put it on wrong. the cap has a #1 on it at the very bottom does that mean that plug wire #1 should go there. the pic is the same orientation that it screws on the distributor

this is what is looks like when all is on. from top left it goes plug #1 bottom left plug #3 bottom right #4 top right #2 meaning the firing order is correct? 1-3-4-2 on plug #4 is where there is the #1 on the cap so does #1 plug wire go there? and could i possible have the distributor in wrong?

#1 is top left, then CLOCKWISE. that might be your problem

and yes, thats where the rotor should be at #1 TDC IGN.

Couple things:

Keep in mind that the motor has two top dead centers, one is on the compression/combustion stroke and the other is on the exhaust/intake stroke. You want it during the compression/combustion stoke. It should be the one marked on your pulley but to be sure, get your compresson tester (assuming you have one), and screw it into the #1 spark plug hole. Take the gauge off of the top of the tester so that its just a hose, wet your thumb and cover the hole on the hose with it. Crank the engine by hand slowly. At TDC for the compression/combustion stroke, you will feel a noticably higher pressure on your thumb. You can also not cover the hose with your thumb and listen to the hose if you like. This is probably the best way to make sure you are at TDC.

After that is done, setting up the distribuitor is slightly more time consuming. The cap on the distrib should fit on so that #1 is on the top left as you are looking straight at the distrib. The rotor should be pointing in this direction as well. Keep in mind that the rotor will turn a good 20-30 degrees clockwise as you slide the distribuitor in because the teeth on the shaft are at an angle, so start with the rotor pointing slightly to the left of where you want. You will probably have to do this a couple times to get it right. When you have it right, the mounting bolts for the distrib should be just about dead center on the sliding mounts (so the distrib can turn back or forward).

Honestly the best way to do this is with a timing light. You can get a rough guess estimate by pulling all of the plugs (and killing the fuel!) and just turning the engine with the starter. You want the timing light to flash at 0 degrees - at top dead center. You can make small adjustments by rotating the distribuitor back and forward, or larger adjustments by pulling the distrib out and putting it back in, one tooth farther over. Keep watching your timing light till you are very close, then start the car and do it at idle (which should be about 20 degrees advance).

Just keep at it... after all the work Ive done with this engine I really feel like this is one of the more pain in the arse jobs. It is pretty much by feel and guesswork when you first start out doing it, but it will become easier. A timing light really helps.

Good luck!

i just removed the 2,3,4 spark plugs and felt out which TDC was harder to turn to, i like fiz's way better, pulling plugs you dont have to is a PITA
