you got to set the points correctly or it wont start if you dont have gauges you can use a matchbook cover between points to set them.move points just till there is a little drag between the points and tighten the lock down screw u must be on the high lobe of the distribor to propley set the points
you have to bring the cam around till it opens the points fully and then you set the gap. if you have a dwell meter and you have a window on the side of the distributor or cap you can set dwell which is setting the gap, just more precise ( although you may not have this window
Mark the position of the distributor. Remove cap. Loosen the distributor hold down bolt.and turn distributor to raise the points cam follower to one of the lobes on the cam. Remove the screw that holds the points assembly. Remove points with the capacitor attached. Put you new points in the same position as the ones that you removed. Points should have .030" gap. Tighten points- hold-down screw. Turn the distributor to the original (marked) position. Tighten distributor hold-down bolt. You should now be able to start, but you may need to set the timing.
The problem is within the timing. Pull all spark plugs, disconnect ignition coil and clear the cylinders to be certain the cylinders are not flooded. Install all plugs, connect the coil and get the timing light and a test buddy. If you have a carburetor then you have points. Clean the points in the distributor and set them back to specification at TDC cylinder one. Look at the orientation of the rotor and where it points. Look at the cap, is it pointing to plug wire #1? It should be. If not rotate the distributor until it is set to TDC cylinder 1. Another thing to test would be a knock sensor or ignition module. Use the timing light to set the distributor angle. Go with the specifications first. If you don't like the acceleration add 2 degrees more BTDC.
Wiper motor contacts are dirty or burnt. There is a cam inside the motor. It is under the casing and if yours has a plastic cover, it would be under that cover.
When you turn your wipers off, it activates a set of points on a cam and this acts like a derailer for the normal back and forth wiper action. The cam sets the wipers to complete a cycle and go to the Park position at the bottom of the windshield.
When the points get corroded you can sometimes file off the corrosion and spray WD40 on the points and they will work like new. Otherwise you will need to replace the wiper motor.
New distributor? new points and condensor? Wires correct? Valve clearance set when cold? The valves need adjustment when new and every 500 miles per manufacturers specifications. New coil? All these are factors.
Dual points are usually a high performance application, and when they are set right they can provide your engine with a huge timing advance curve, as compared to a stock application. The points open and close sending a dwell signal to the ignition coil telling the coil when to fire the spark plug. They are a lot better performance wise, but they are also trickier to set properly. I can do it because I have set so many of them.
Well you have a good BMC there so set the tappets to 12 thou , but check the wear on the rocker bushes first as they have the point of wearing on top and bottom and setting with stact cold some times still rattle so the best way to do them is start run with rocker cover on warm up to thermostat open then remove rocker cover and set throttle to low idle and run andcheck with 12thou push in and out ,if 1 or 2 are noisy
adjust running to 12th.
Points set also to 12thou with points open to any one cylinder and push cam towards the points with your finger and if it opens to 15 (which it will) then set points to 10 as when auto advance opens up 3deg BTDC
the points go to 15 and your spark could give you a problem at pulling power, also auto advance weights in distributor will send points to open up sooner ,reset throttle to 550 rpm and away you go .
Have a good run
