I’ve been able to get some flying time in this summer. I put a few hours on an Enya 46-4C II with spark ignition. It has a CH Ignitions<\/a> system installed. I bought it online at auction. It’s old, there was a note written in the box, “Run 6-28-88.” It uses the mechanical timing advance arrangement. I had some trouble tuning the engine initially, but it must have not been broken-in fully. After a couple hours of running it smoothed out, runs, and tunes well. I’ve been running varying percentages of castor oil (Maxima Castor 927<\/a> or Klotz Benol<\/a>) or Klotz Original Techniplate<\/a> with either straight methanol or E85. The E85 runs well, just a few hundred RPM down from methanol. I’m tempted to raise the compression ratio to increase performance.<\/p>\n

Another project is an OS FS-52 spark conversion. It will have an RCEXL spark ignition. I see these systems are rated to 8000 RPM, so I’ll see what happens above that. They require a 1\/4″-32 spark plug boot with resistor to be installed as they are supplied with boots for 10mm or 14mm plugs. These ignitions are mainly used with large 20+cc gasoline engines. The engine is also receiving a positive crankcase ventilation system like OS uses in the new FSa series. I hope this will keep the oil mess down and allow me to reduce the oil content in the fuel. I made a gasket for he rocker cover and sealed the backplate with anaerobic sealant. I also intend to try this engine with E85, and after some runtime will increase compression ratio to see if any power can be gained.<\/p>\n

Diesel four stroke projects continue. I’ll be adding the crankcase ventilation system to my FS-48 along with a few other parts to freshen it up. Again, I hope to be able to reduce oil content in the fuel from the 10% I’m currently using. I hope to test fly the FS-91 in the coming weeks. The engine has been waiting since fall of 2007. I am also contemplating the OS FS-120 diesel conversion. If the .91 runs well on the airplane, I’ll try converting the 1.20.<\/p>\n","protected":false},"excerpt":{"rendered":"
