| Wst. FILE 6017. 2.6.37 PHANTOM III. COILS. 33-EX. After following the routine jobs in trying to cure a misfire (pick up and slow running B. distributor) we changed the coils over to see if the trouble followed the coil. This cured the misfire on B. but A.{Mr Adams} was also O.K. We demonstrated this to R.Swindall. From this we gather there is a variation in standard coils and secondly a higher output is necessary from the coil to fire inlet plugs than exhaust.
