do these motors really chomp up carbons as quickly as this?
1x zwf1432 2yrs 1 month…
1x zwf1421 2 yrs 9 months…
1x zwf1621 1 yr 20 months…
1x zwx1637 3yrs 10 months… (elderly once a week user though)
all worked on within last 10 days, all carbons virtually non existant!
just wondered if anyone knew if the oem spec was for a really super soft carbon? its just odd cos the 1421 had been arcing something chronic because i assume there was absolutely nothing left on one – tight to the plastic holder, and ive got a nasty feeling the armiture will be shot on it too but we shall see…
