0.8 to 0.9 mm
Spark plug gap should be .025 http://store.chainsawr.com/
If it's an 8 valve engine and not the 16 valve: Bosch Spark plugs have a gap of 0.8mm NGK spark plugs need a gap of 0.9mm 16 Valve engines have a 0.9mm gap on each type of spark plug
anywhere between 16 and 18 on a spark plug gauge should work fine.
35mm
the proper gap is .016 or 16 thousands.
20 to 25.000 points 16 to 18.000s
Standard gap is .060" or 1/16".Ask at auto parts counter when purchasing spark plugs.
disconnect the negative battery cable remove the spark plug boots and make sure you know witch one goes where remove the plug use a 5/16 spark plug socket gap the new plugs to 0.041 in apply antisieze to the threads of the new plug apply a little silicone dielectric compound to the end of the spark plug lead install the spark plugs and tighten to 16 ft lbs put the boots back in annnnnnd your done.
Take off the gas cap. Take off the big plastic cover with a socket and wrench.Then put the gas cap back on. Then pull of the spark plug boot. Then take off the spark plug with a spark plug socket and wrench. It should be 13/16" socket with 3/8" drive wrench. I Think the spark plug gap is 0.025 but you would have to look at a manual.
Depending on the year of the car, and (for later models at least) whether it is 8 or 16 valve, the gap is either 30-thou (0.7mm) or 40-thou (0.8mm) If your car has 2 or 4-electrode spark plugs, it is usual for these to be replaced if the gap is excessively large.
