	As per shop manual, SN 9001 and down (Series I) and smaller engine has two different plug options.....one for heavy loads, one for light or med. Plugs listed for Series II (9001 and up) and 160 engine are different than either option listed for Series I.....but no load range specs. Series II has only the one set listed vs. two. And still find it odd that for Series II, specs and data in the shop manual is only 1 paragraph or so vs. nearly 2 pages of specs for Series I. Downright scarce.....which leaves us to guess.....which is a bit scary as clearly they are not the same. Edited by modirt - 25 Jan 2021 at 2:51pm

	What are good modern era numbers for replacement spark plugs for the D15 II, with 160 motor. Book calls for AC C45, Champion J-7 or Autolite A-5. All seem to be obsolete numbers. Now has Autolite 303. But not sure if that is right.
