Then as far as magnesium itself, yes you must be careful. Magnesium grindings or shavings can be accidentally set on fire by a spark, and it burns white hot with a fire that cannot be put out with water. So you need to clean up often and safely dispose of it. If you do not let too much accumulate at a time, you'll be fine.
Here is my post and pics of the Stihl 62cc that I converted.

I did not know that about the magnesium cutting precautions, many thanks for that. I will have to chase up some carbide cutters and a suitable power tool to do the job. Maybe a carbide blade for my little 4 inch grinder is available? I only have a carbide blade for a 71/4 in power saw, which is far too big.
Thanks for the link to your thread above. I had seen it, but not studied it closely enough. The principle will be very similar. I was a bit stumped by the challenge of making up an intake manifold adapter; your idea is neat and simple enough for me to copy.
