Dear Dar,

tried resetting the slow speed needle valve but results were the same - 4 min fligt followed by a dead stick. Thought the engine was lean, so i richened teh mixture, but the result was the same. The slow speed needle valve is the old one( blunt tip) . I have now replaced it with the new one ( tapered tip) any suggestions as to the start point/settings ?
Thanks
Rajeev
