Thanks AVB, Gadge and Jack
I finally bit the bullet and ordered the carburettor kit. What a difference a couple of pieces make. Starts on about the third pull, and runs fairly well. I have not had the opportunity to try it under load yet. I am not sure that I have the governor hooked up correctly just the way it was when I got it but there are not many possible combinations so I should be able to nut it out if need be.
It has a bit of a knocking rattle coming from the top of the motor, if it was a newer machine I would be a little concerned, but I suspect these older motors always had a few rattles. It is not the sort of noise I would associate with a main bearing but could be a broken ring, or a camshaft problem. Maybe a gudgeon pin.
Any how thanks for your help, it is a joy to see it running and well worth the cost of the kit. I could have spent that much money on something that would have been gone in an afternoon and left me with a head ache the next day. Thanks to Outdoor king for sending the parts express, WA actually stands for wait awhile so I did not expect them until next week.
