Got some O-rings today, put it back together, fresh fuel (not even sure it needed that) put it to start, gave it a couple of primes and about 10 pulls and no joy.

Put it to full song 2nd pull and away it went. Coughed and farted a bit then started singing.

Throttle cable wasnt right it was cutting out before the choke position.
Thats the wrong filter housing on it in the pic, pulled it all apart, adjusted the cable found a mint housing the same as the one that came off it originally. Put it back together and its all sweet.

Will give it a wash tomorrow and take some pics.
