Step 2 Removing Burrs

Next you will need to use a file to remove any burrs left from cutting the ground electrode. If this step is not done the burrs could heat up until they glow red hot causing detonation. After the burrs are removed you will want to use some alcohol or starting fluid to thoroughly clean the plug to make sure there are no metal filings left.
