My latest attempt to run mogas in my Superior O-360 was not good. I had good luck running it until the temps warmed up and then problems. I suspected that my rough idle was due to mogas so I drained one tank and replaced the gas with 100LL. No problems in the flight around the patch. After landing, I switched to the mogas tank to see if it was indeed the problem. Sure enough, before I could return to the hangar my engine was barely running; coughing and loopy idling. Super I thought; no engine problem just mogas.
After I limped back to the hangar, I felt my right brake go soft. After shutting down, I noticed an ever larger pool of brake fluid forming around the right tire. I rolled the bird back in the hangar and within a few minutes, I had a pool around the left tire. I thought that the vibration might be enough to brake the al tubing that runs down the gear leg. I ordered braided lines and installed them this a.m. As I went to reverse pump/bleed the brakes, fluid immediately started running out of the brake caliper. I had not found any breaks in the al tubing so I was already questioning my analysis.... now I am baffled. Ideas please.
