Hi Grumpy, I don't know the history on this machine except that it was recently purchased second hand.
On disassembly is appears to not have been apart before. I can't seem to find any info on it but it has a felt air cleaner that seemed to be oiled perhaps a tad excessively as it was all over the carb. I'm not sure if they are meant to be oiled but I pulled the carb down and rinsed all the oil residue off and also washed out the filter and I reinstalled it dry just till I run it for the first time which I didn't get a chance to do today.
I have nothing to check the metering level except to say that it is level across with a straight edge.
The plug was really carboned up flush to the top of the insulator cavity. I have cleaned everything up and will hopefully run it tomorrow arvy and see what happens.
