Depending on how many cigarettes you are smoking every day, you may have either a small or large amount of nicotine in your system. As a guide, nicotine usually lasts between 2 to 14 days in the urine, 2 to 15 days in the blood, 1 to 4 days in the saliva, and between 30 to 90+ days from last use of nicotine products.
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.
The ignition coil is the part of the ignition system that generates high voltage to the spark plugs in order to ignite the air/fuel mixture in the cylinder. Ignition coils are compact electrical transformers that boost voltage as high as 40,000 volts, which is the level needed for proper combustion.
