[1965GTOTempest]

When my car went in today for new hinges and hood springs (pics later in the week), I asked my mechanic to lower the timing a bit as she was dieseling a little. He had set it at 12 but lowered it to 10 for me.

ICK.

As soon as I drove off I knew I was fu**ed and wasn't going to enjoy it. She has that bad hesitation you get when timing is retarded.

But I also noticed was she's shaking like Kate Hepburn when I'm at a stop light, and the muffler "sounds" louder to me ... she's rumbling more. I figure that's because the idle is up a little (850) so I need to have that lowered a bit (or I'll get shin splints trying to keep the brake down).

But the shimmy shake -- is it because of timing? It didn't even do this when timing was retarded at 4!
