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.
Use caution when building coils. Always check the resistance of the coil on an ohm meter before using them on your mechanical mod. If the build is shorting out, your battery is at serious risk of damage or catching fire. The resistance of the coil can vary, so use the figure given plus or minus 0.2 ohms.
