kyle:

manual says .028" gap, but most plugs, such as the autolite 403, are made
for about .035", which is a good all around gap. 2 mm is about .08" - an
extra wide gap - there are plugs manufactured for that, but if due to
excessive wear, then plugs should be replaced, irrespective of deposits.

hall sender and coil not likely culprits. almost all coil replacements are
unnecessary.
