Spark Plug suggestions

[Jeff65]

Take your plugs out and look at your existing plug tips. The tips will tell you how well they're working.

a. If black and dry, they are too cold for your driving habits. Get a hotter plug from your parts store.

b. If black and wet then: wet with oil, need engine overhaul, wet with gas, need tune up or carb work.

c. If very white flaking or rosy insulators, look for destruction of insulator tips, plug is too hot or incorrect fuel octane.

d. Should be light grey insulator tips, fading to white, no evidence of electrode wear, no misfires. In this case you have the right plugs installed.
