Post: # 18688Post LFP »

NGK BU8H plugs(On-line: $1.84) are semi-surface gap and don't have the big well alongside the electrode to collect fuel/oil. Replaced heat sensor as it seemed enrichment circuit was on while engine was warm. New sensor has mounting crush material insuring positive thermal conductivity. So far, so good.
