[Greg Reimer 7376]

Back in the early/mid '70s, the era of the most horrible performing cars on earth, a guy backed his '74 Cadillac out of his garage, got out to close and lock the door, and he left his car running on fast idle-around 2000 RPM or so. The phone rang, he ran inside to take a call, which lasted about fifteen minutes, and the car ran at that speed the whole time. He got off the phone and came out to find the cars' exhaust manifolds, the Y pipe, and the head pipe to the muffler cherry red hot. He panicked, shut the engine off, whereupon it dieseled like crazy for several minutes, and then backfired and quit. He had no idea that a by product of retarded ignition timing and a late closing camshaft was excessive exhaust heat. He's lucky he didn't burn the whole place down. Set the timing to 36-38 degrees at 3000 like everybody says, and I bet you find that the engine's idle improves significantly as well. Good luck, let us know what happens.
