My C43 as developed a anoying starting problem the engine turns over fine when cold but once the engine as run for a few minutes the starter will operate for just a second then turn off, this procedure as to be reapeted several untill the starter cranks long enough to fire the engine. I fitted a new starter which cured the problem for several months but now the fault as reoccured, the starter makes a dry squeek when cutting out . Is there a special lubricant for the starter to ringgear drive? the starter works fine if powered from the battery direct. Any ideas much appreciated Thanks Linds
