jasonm. Posted December 1, 2011 Share #1 Posted December 1, 2011 (edited) if you have the latest December 2011 MCN. Downtime files has my letter. Seems he does not have a "for sure" answer to my question. I did have an issue with #2 carb, which is now fixed. But that does not explain why all the NGK caps and spark plugs failed. He thought maybe oil got into the caps. FYI- No, that's not it. I truly believe NGK is now making junk(which I have stated before). And think about it. OEM caps are roughly $25-$40, NGK $4. So you get what you pay for in this case. I have a total of 6 or more bad spark plugs from NGK in the last 3 years resistor and non-resistor. Remember the spark plug is simply an extension of the wire connected to the engine's coil for spark to jump in a hostile environment. I NOW have changed the caps back to OEM(10k ohm) and spark plugs to Denso iridiums. Plus all my carbs set up on low speed screws at 2.5 ccw +/- a quarter turn connected to EGA . 13.6:1 at idle. And were not rich when tested on load. ...cheers:) Edited December 1, 2011 by jasonm. Link to comment Share on other sites More sharing options...
