Update On My Hard Starting O-360.
I wrote about a week ago on my hard starting O-360. I got a bunch of responces, and went to the airport last weekend and checked my engine. I checked the timing on the mags. I figured if it was an impulse problem, I would see it in wrong impulse firing time. My mags were timed perfect and the impulse fired at 2 degrees after TDC. I checked the plugs and they looked perfect. I decided to change the four plugs on the left, starting, mag just because it was the easiest point to start at. I got myself a set of four tempest plugs and installed them last night. I pulled the plane out of the hanger with the cowl off and tried to start it. She started instantly. I put the cowl back on and went for a little flight. She started instantly again. I'm ordering another set of four plugs, the tempest plugs look real nice by the way. Thanks for the responces guys.
