Coil resistance? My book says my coil resistance should be 4.0 Ohms (+/- 10%) on the primary and 9.5K on the secondary (+/- 20%). Unfortunately, I get 2.9 and 2.7 Ohms (more than 25% off) and 20K to 18K (like 100% off). Any time I use the electric starter on a cold, choked engine, my plugs like to foul.
