Hi CyberJack,
I read somewhere here that the G4 based LM plastic carburettor was released in 78 and this featured the primer bulb built in to the white cap. I have a 125 mower with this primer cap along with the label pointing to it. Was this label put on as part of the service bulletin to retrofit the primer bulb cap in place of the plain grey primer-less G4 cap?
I have seen two 125s with what appears to be an LM carburettor with the white cap with the black label pointing toward the primer bulb, which suggests a probable factory fitment of the LM version of the plastic carby to the 125. one of them is mine and the other I saw was a neighbour's.
If the label was only fitted by the factory, then this points to the 125 mower being built in 78.
