black soot on plugs 4 and 2

Post by John Alves » Sun May 17, 2020 1:14 pm

Hi All

I have a 1500 sp motor in my beetle which occasionally fouls up plug no 2. Plugs 1 and 3 are fine, plug 4 has slight black soot on it and plug 2 has lots of soot on it, how is this possible? valves are correctly set.
If I lean the carb then the motor runs like crap any ideas?


No sense being pessimistic. It wouldn't work anyway.

If you currently have NGK plugs, try exhanging them for Champion L87YC
