Sorry Paul haven't had a lot to do with the G3's, any that work I use but now that I can fit the G4/LM to them it is just so much easier and parts are readily available for them and the G3 is getting harder to find bits. The LM type will still be around for years to come. I am not restoring mowers so having the correct carby is not a problem to me, I refurbish them so they can go back to doing what they were designed to do, cutting grass
