The last month has been a bit frustrating. First, the Spring Air retract gear was substandard and had to be replaced with Robart struts still using the installed Spring Air retract actuators. Then I had problems with the engine wanting to die when slowing in the pattern for landing. Bubbles were seen between the needle valve of the the OS91FX engine and the carb. The engine had the old/original needle valve design which was prone to bubbles. I then ordered a Cline Fuel Regulator and a new OS91FX and they were installed this week. Ran two tanks of fuel through it yesterday for breakin and flew it three times today for its first flights with the new engine and fuel system. After a few more engine breakin flights I hope to have a good report. The plane flies beautifully and now if the engine stays stable, which it was today, she will be perfect.
