No Spark

[nigeldtr]

Does anyone have any experience with the special plugs like in the BR7EIX iridium? From what I can read, this should be better for the spark and burning off the fuel (being careful here :-)). Not surprising the B8ES fouls quickly, it is probably far too "cold". With large std electrode, poor grade fuel, it probably can't get hot enough during the start and warm up phase to burn itself clean and dry? Interesting theory now just need to buy some new plugs and  put it to the test!

The Notrun riders down here swear by the iridium plugs, then again getting Notruns to run reliability is a full time job regardless of the plugs used and Notruns are at a bit of a higher state of tune than most of the pre unit A series.

Once I get the new caps I will have another go. 

Don't wait. Just attach the copper core of the leads to the plug terminals.

HI Nigel,
To the best of my knowledge, on  "BR7EIX iridium"
the R means resistor!!  see here
http://www.ngksparkplugs.com/docs/tech/partnumberkey.pdf

therefore not suitable for mag ignition!!

I tried running irridium plugs in the a10 and my super meteor.  I changed them back after less than 100 miles.
Cheers,

Denso make iridium plugs without the resistor.
