Good works all ! .

wd40 and other solvents should never be used on chains because it washes out the little lubrication it had & won't allow the new lube to get it , then it evaporates & you'll have a dry chain .

Anytime you touch the points , you *MUST* then check and re adjust the ignition timing again as .001" change in the points gap , changes the timing by 3 degrees .
