Ciao!
I feel comfortable to suggest you
http://www.lrc-components.it/ the web site is in Italian, but with google translator it will be easy to navigate, I know that they send worldwide.
About the ignition coil, try to have a look here
http://www.lrc-components.com/-compo...obine-complete I suggest
http://www.lrc-components.com/-compo...?product_id=64, it's the most common on BZM's engines.
I don't know the petrol company you have in Russia, but I know that the standards in Russia are litttle bit different than in Italy, you can use 96/98 octane fuel adding 3% of
100% sinthetic oil, the bests are Bardhal KXT or Motul 800.
