Some newbie questions about Bamford EG1

Hi All,

Just got my first engine, a Bamford EG1.

I managed to get it running but I think it could do with a new spark plug. Where would I get one and what should the gap be?

The Choke appears to need to be held half to 3/4 closed to start. Should it have some locking mechanism on it or do you just hold it where you want it against the spring?

Can I use general purpose grease in the camshaft grease cup?

Any other tips for these engines?

Cheers,

Richard.
