Hello,
Should I, or May I, use a hotter plug with dual carbs? I have NGK B6ES in there right now. One range hotter would be a B5ES, Right? I seem (or think) to remember with my 67 BSA that NGK gets hotter the lower the number. 1.7 liter with dual weber 34 ICT. 009 dist with regular old points. Many thanks to you. |

I had a 67 911 that ran rich and seemed to fowl plugs so I ran plugs that were 1 level hotter and it ran like a champ from then on!

Manufacturers are often very conservative and usually specify a plug on the cooler side of the heat range. So running one index hotter can make a difference. However, did you ever determine why you were running rich? A comparison might be adding more and more oil rather than fixing the oil leak... Oops, sorry, this is a 914 board; Of course we keep adding oil (IMG:style_emoticons/default/biggrin.gif) Eric |
