One last question for the evening: What kind of sparkplugs are preferred? Brand, type (forked tip, platinum....) And is it worth getting the micro-washers/shims to get the spark lined the "right" direction for the extra burn? And what is the "right" direction? Thanks... I'm going to bed now and look forward to answers and flames in the mornining. :) [Non-text portions of this message have been removed]
