To add to the plot a mate called round today . said 5 of them went on a run last year. all filled up at that station and ALL broke down
What is the equivalent champion plugs for the ngk 7's and 8's ?
NGK lower number is a hotter plug ..Champion lower number is a colder plug
A b8es is equivalent to a N3
if you take away the plug number away from 11 it will give you the other make equivalent
So an NGK B7 is eq. to champion N4( this method dosent work for the entire range but does for the common lammy plugs )
But i use a N3 in all my engines with no problems Std 200 to RB240

Cheers russ i will get some and see how it goes.
Took the special out for a run yesterday and seemed fine on same plug/petrol.
except for one time i forgot to turn the fuel off and needed a few kicks.
dont have a problem with the vespa. wonder if the flooding of lambrettas could affect the spark plugs to break down ???? i regularly forget to turn the petrol off on my lammies
