Thanks Grumpy. Knew this would be right up your alley. cool
The guy who gave me the mower paid a considerable amount of money for it some years ago so I thought it would be a decent model. Thanks also for the links to parts and user manuals. I have got the mower starting no problem and there is no blue smoke from exhaust. I had the cowling off and the air vane moves freely. I only purchased new air filter element on advise of my old man who said engine would not run with the old one all clogged up with oil!!! I'll instal the old one back on and keep the new as a spare.

Cheers
Mark
