Before I went flying today I replumbed the tank and changed out all the other lines, I didn't find any obvious holes in any of the lines but I did notice a few deep abrasions in a couple of the lines. So with that done off i go to the field, once there I fueled up and I would not start (still had bad plug from yesterday in it). Oh crap i was out of the Mccoy plugs, I know the Os plugs have not worked in the past and all I had left was a very old Hobbico 4 cycle super plug. I put it in and fired it up there where no bubbles visible at low throttle and up to medium it still looked good, so I floored it (so to speak) no bubbles and the motor ran strong, it tached at almost 16k. Refueled it and off it, went my timer is set at 6 mins. and it has an 11oz tank. I fly this bird pretty much wide open all the time and when that times sounds I had better be getting close to the runway. 3 flights today and no problems at all..
