      Hi Guys
      Was wondering if you could offer some advise if you please.
      I finally managed to get my engine started after loads of attempts.
      I started off with a max jet of 92 which was very rich as the spark plug was black with oil.
      Then last night i came down to a 85 max and although not as rich as before , but still seems to be as the plug is still dark.
      It puffs out quite a bit of smoke, and as soon as i pull the choke it stalls, with the 85 jet it does idle now as with the 92 it didn’t so some improvement there but performance doesn’t feel as it should be.
      The idle jet is a 48 and the starter jet is a 60.
      when i accelerate it does seem to be quite slow in take off even though i have a vario, and smoke puffing out, so by this i assume it is still rich.
      I am a little scared of dropping to say an 80/82 as i don’t want to damage the cylinder.
      Rather than changin another jet and maybe risking being too lean would it be an idea to play about with the gold mixture screw ?
      Oil is at 3% for first start up.
      Any help would be appreciated.
      Giuseppe
