  1. If you lean your mixture till you get no soot you will be running way to lean when at normal cruising power you cant judge mixture by cht or by plug appearance

     

    try swapping the plugs around and see how quickly they get soot on them during idle runs

     

     

  2. What are you looking for after you lean the mixture IE what is the problem with the setting at the moment

     

    As has been mentioned in the earlier posts the only way to check mixture by looking at the plugs is to shut both mags off after a sustained high speed run which is not possible

     

    even taxing for a few minutes will cause black plugs on two cylinders

     

    and if two cylinders are running rich and you back the mixture off the other two cylinders will run lean

  3. Ours seems to take longer to burp if it hasn't been flown for a while I think the longer it sits the more oil seems to accumulate in the sump which means longer time to return all the oil to the tank

     

    cold weather also makes it harder to burp

     

     

  4. Ours take quite a lot of turns to make it burp especially if you turn it fast it you turn it slowly and hold it at the top of compression it burps a lot faster

     

    what is happening to the oil level when you cant get it to burp is it low on the dip stick or at the normal mark

  6. Last trip was a quick overnight flight in the RV12 from Latrobe valley to Tocumwal left lunch time and had a great trip nice and smooth and a few clouds this side of the ranges and clear the other side bit rough descending but not too bad Landed and tied down and got a lift with a club member into Tocumwal booked into the to Tocumwal motel for the night Went on the courtesy but to the golf club for tea. Walked out to the airfield topped up with fuel and flew home in the morning also a great flight very high cloud with a bit of light rain coming from the west about an hour and a half each way and 65 litres of fuel

  7. I used lighter springs and it still creeps a little so I loosen the friction to adjust throttle and then loosen it when I want to adjust it sounds fiddly but soon becomes second nature have considered fitting vernier throttle but it is pretty dear

     

     

  8. thanks alf I will have a look at the figures from my last trip and do a comparison My skyview fuel flow reads a little high normally and a bit higher again if I do a lot of taxiing or idling as it measures fuel to the engine but not the return fuel
