OK... thanks for all good tips and advise. Today I replaced the glow plug (I knew the old one was fine - I just wanted to be certain) with an O.S. A3 glow plug. Then I filled the tank with new fuel. I set the HS valve to 2 turns out and the LS valve to 1 1/4 turns out. I started the engine and left the glow driver connected for about a minute or so. Then I disconnected the glow driver and the engine seemed better. I ran it like this for few minutes to make sure it won't stall. I had the adjust the HS needle valve when I had the engine running at full throttle... it's set at about 1 3/4 turns out. I have a feeling the the old fuel was bad because the new fuel seemed to help the engine to run better. I will work on it some more to make sure the needle settings are where they need to be.

Thanks
