Had to get new heads for the dragonfly. It has a limbach l2000 which is basically a Volkswagen type 1 aeroconversion. The old heads were done so I purchased a new set with 40mm x 35mm valves. This in turn necessitated a conversion to auto plugs for the slick magneto which I purchased premade through g3i ignition.
Right now the idle is high 1300-1400rpm, and it’s running slightly lean. I expected both of these issues. Just a little bit of tuning and it should be good to go.
With the new heads the differential pressure test came out to 79/80 on cylinders 1 and 2, and 78/80 on cylinders 3 and 4. I couldn’t be happier with those results.
