Yes, you for sure will get a shock as there is from 40,000 to 100,000 Volts DC at the spark plug. Although it is DC voltage and the chances of getting killed are not as great as with AC voltage, it is possible if you were standing in a wet area and were grounded sufficiently. You will for sure feel it and believe me it hurts.
The wires need replaced.
If you have no gap meaning the electrodes are touching then the spark plug is being grounded therefore causing a no spark situation. There has to be a gap in order for the electricity to jump from the electrode to the ground.
You can check for spark by removing the plug wire from the spark plug and holding it about 1/4 inch from ground. Have some one crank the engine or pull the starter rope and look for a spark to jump from the spark plug wire to ground. DO NOT hold the wire with your bare hands since you will get shocked. If you have spark there, remove the spark plug and insert it into the end of the spark plug wire and do the same procedure. If there is no spark, the plug is bad. If you have spark, the problem lies elsewhwere.
spark plug gap is.044
spark plug setting should be .044
Spark plug setting should be at .31
The spark plug gap for an AR135 spark plug on a 350 SBC should be set at .034 inches. This is equal to .86 mm so a spark plug set to .9 mm should work correctly.
A 1968 Ford Galaxie 500 with a 390 engine should use a spark plug such as an E3 brand spark plug. This plug should have a tapered seat with 18mm threads.
Spark plug gap should be .060
Spark plug gap should be .025 http://store.chainsawr.com/
Remove the kill wire from the ignition coil. It's the only wire that doesn't go to a plug. Remove one of the spark plugs. Reconnect the plug wire to the plug that has been removed. Make sure the threads of the plug are touching metal on the engine somewhere. Crank the engine. Should see spark. If not, bad coil.
The spark plug gap for a 1984 Toyota Corolla should be set at .044 inches. The best spark plug for this vehicle is an Iridium plug.
