My dog is an Australian Sheep Dog, he is rambunctious, very friendly, and fast enough to catch any cats who stray into our yard. He doesn't hurt them though, he simply runs over them, as in, he steam rollers them. It really makes them mad.
I have my 125-a set up to run again, the timing is set at 33 degrees btdc. I might change it to Gary's recommended 35. The prop is a 15 x 7 MA three blade,(picture is a Graupner G-Sonic 15 x 8. I've lost the numbers and need to re-establish them. The smoke is due to the picture being taken when it was about half broken in. As you can see by the oil pool it was still rich.
