It was a reasonably tight fit but not one only possible with gynaecological skills! Could send picture if any help.

During the winter months, awaiting an opportunity for weighing the airplane, I kept the Europa with empty tanks. (Weighing has been done by now: 421Kg, CG exactly in the middle). Now, in preparation to first flight, I decided to fill the tanks again. After I swicthed on the fuel pump, I noticed that my fuel flow gauge indicated a flow of 2.5 L/h, without the engine running. I thought of air entrapped in the sensor, until I noticed that fuel was leaking from the cowling. Further investigation revealed that the overflow of the airbox on the port side was spilling fuel. Fuel pressure is correct. So, I guess there is something wrong with the port carb. So far, for all my Europa related problems, someone on the forum could help me to find a solution. Before I start disassembling the carburator, I would like to get a confirmation that that is what I should be doing, and if there is anything else that could be the cause, or if there is any other solution, I would like to hear. First flight can be performed as soon as weather cooperates and a suitable test pilot has time for this, so I hope this problem can be solved without causing a delay.... Thanks in advance for any insight.

Frans, Off the top of my head, I'd guess a sticky float or restriction in the fuel return line. Any other ideas out there?

Dave From: jimpuglise@comcast.net Subject: Re: Europa-List: Antenna tuning David- I assume you are talking about the copper strip antenna that comes with the kit. My own approach is to start at the bottom of the band and record the SWR every 50 khz. After you have done this=2C put the figures in Excel an d graph it. Each line in your Excel spreadsheet shoud have one frequency i n column A and the SWR at that frequency in column B. In this way=2C you c an see what the antenna is doing through the entire band. You need to be c oncerned that the SWR is not extremely high at one end and extremely low at the other. I usually shoot for 1.0-1.2 / 1 at the center and 1.9 or so at each band edge. If you are at 1.5 in the middle of the band=2C that shoul d be just fine. The reason you are not seeing change with small adjustment s is that it is probably relatively flat a few MHZ each side of resonance. Also=2C I don't know if you are using the coax that comes with the kit=2C but I took one look at it and threw it away. Invest in some good RG-58 for the comm antenna and some RG-400 for the transponder. When you look at th e graph=2C it will be very obvious what you need to do.
