Re: Battery CDI Problem
Walker..... The points are to be set at .010 . While setting them, turn the flywheel and check that setting on all of the high lobes. The settings may vary from lobe to lobe. You want the widest setting to be .010, not .012 or /013 .<br /><br />The over-rev spring that is mentioned in the orther post is actually a Reverse Cutout Spring. That engine is capable of runing in the opposite direction.... that spring prevents that problem.<br /><br />The intermitent spark problem.... when you encounter that, remove the coil wire from the distributor cap and double check the spark directly from the coil. If the spark is okay there, you will know that the problem is with the distributor cap, rotor, somewhere in that area.<br /><br />You can check the powerpack out as follows.<br /><br />(Battery Capacitance Dischage Powerpack Test)<br /><br />Purchase a small 12v bulb at your local automotive parts store (the 12v bulb is to look like a flashlight bulb, not a headlight bulb). Solder two wires to that bulb, one to the side of the bulb (ground), and the other to the positive point. <br /><br />Remove the spark plugs. With the key in the on position, make sure that you have 12v going to the pack at the terminal block (purple wire). Now, connect the ground wire from the bulb to any powerhead ground. Connect the wire from the positive point of that bulb to the powerpack wire that is connected to the coil wire on the terminal board (blue wire). <br /><br />Crank the engine and observe that bulb closely (CLOSELY!). If that bulb glows even the slightest bit, the powerpack is okay. It may be a very dim glow... just so it glows! If it doesn't glow, the pack has failed. <br /><br />Keep in mind, that type powerpack (Battery Capacitance Discharge) demands a top notch battery of at least 70 amp hours. Any less will, in time, cause powerpack failure.
