Re: '70 85hp Chrys. won't start
First, check for spark on all three cylinders, remove the plugs one at a time and hold with a good pair of insulated pliers to a good ground make sure that the threaded part of the plug is up against the ground, and you can see the electrode on the plug. Then have someone ckank the engine, you should have a blue spark. If no spark clean the electrical connections with sandpaper until they are shiny again pay attention to the wires coming from the distributor. I would also remove the distributor, make sure you make a mark on the belt and the gear so you know how to put it back together. Then remove the points and sandpaper them and set them 0.014. Then reassemble and recheck for spark. If you have spark post it and we will go from there. Do you have axcess to a compression tester?<br />Good luck
