I talked with the Dulles FSDO inspector regarding getting an airworthiness inspection. He said I needed to do a flow test to determine if my fuel system could deliver 150% fuel at full throttle, low fuel and max climb angle. How to do that with an engine-driven fuel pump has been a mystery. The KRnet has been most helpful with suggestions. My hangar partner had removed the Grand Rapids fuel flow sensor from his Pulsar XP. The aircraft has a Rotex 912 with dual altitude-compensating carburetors with fuel return to the fuel tank. The fuel flow sensor was not suitable for his installation, so he gave it to me. I am now installing the fuel flow sensor in my KR-2 2180 VW to plug into my Grand Rapids EIS. This will be a permanent installation. I am also temporarily installing a "T" in the fuel line at the carburetor. An 8-foot fuel hose runs from the "T" to a valve. This allows dumping fuel in a can in addition to supplying fuel to the engine for the full Power run up. My assistant can then adjust the valve to get 150% flow through the system, while I monitor the fuel flow numbers from the cockpit display. The 2180 VW is limited to 2 minutes full throttle operation at sea level and low altitudes. That should be sufficient time to do the actual test and prove the carb has not run out of fuel. Have to test each of the 2 wing tanks in the fuel system. I will remove the "T" and extra fuel line to return to normal operations. First flight and Gathering 2012 are on the horizon.
Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA smw...@md.metrocast.net ------------------------------------------------------------------------------------------------------------- Netters, As I sit reading another E-mail about putting a Jabiru on a KR, I thought that I should give you an update on my progress of getting to the next gathering. The situation that I am in right now is like a puzzle. I have a plane in my garage, not a KR, an Ultra PUP. That is another story. Prior to going to the Gathering, I was helping a fellow EAA member and KR owner do some repairs. He purchased an older KR tri gear that needed some minor repairs. That was 2 years ago. He asked me to help him with some of the repairs, glass work on the cowl, cracks on the canopy frame and cracks in the paint on the wings as well as some bubbles on the wings. When I decided to go to the gathering, I called him and said that I would be able to help him, duh!! he offered some money for the fixes and me going to the gathering,,,, ,well it was a win win. I got the cowl fixes done as well as the canopy frame and I primed and pained them prior to the gathering. Since I got back I have been working on the wings, and let me say if you are going to use BONDO as a filler.....dont. It will crack. If you do, spend the extra money and get the good stuff. Wal-Mart does not sell the good stuff. What I thought were going to be easy fixes, could have been if I did not not like the person that I was doing the work for. Several grinding disks later, and some micro filler later, the fixes were ready for the good body work. I should have the wings in primer this weekend and ready for paint. I found out today I need to help a family member move and will lnot be able to get the paint on this weekend. I will find a night this comming week to get it done. With that said, I can focus on the plane in the garage and get a coat of paint on it and get it to the airport. Snakebite will then have all of my attention. I would like to have it back in the air before the new year. OK lets hear the progress stories.
