Thanks for all your replies
Some clarifications/questions:
Don't know what LSN is and how to reset?
I have been trying to find the manual online with no luck. So thanks for the Mecoa guide suggestion. I will read through it.
I used a new glow plug te first time when I got it to start which was a week ago. Should I sill replace it. The glow plug ignitor meter shows green when plugged.
I am already using a electric starter as I don't think there is any way this engine will start manually.
How can I move the post to the engine section or will the moderators have to do so.

Thank you for all your suggestions. I feel I am more armed with things to try the next time I get to play around with it.

Also I forgot to mention this but I removed the cylinder head and used a little bit of WD-40 spray hoping to smooth out the engine and remove any goo.
