No they don't glow, the cam I have (Erson 453 lift) was matched to the build of the engine by a local speed shop and Erson said to set the timing 4 degrees +. I have a timing tab that gives a 4 degrees advanced tab, at 1000 rpm I show dead 4+ with a timing light. Am I missing something with this?
If Erson said set timing at 4* they probably meant to install at 4* advance, not the running timing on the harmonic balancer. i've never seen a cam company tell you what to set the engine timing to. I would get or borrow a timing light with the ajustable timing control, and bring the rpm's up to about 3,000 rpms and set the timing to 36/38 degrees total timing.
As Todd says total timing not idle timing.

Thats what I was thinking John, +4 on the cam, not initial timing.......
Add more timing to it, at least 10 BTDC for starters, then if she still runs warm jet up on the carb about 2 sizes square, a lean carb will warm things up with a quickness, that coupled with a slightly re-tarded motor ( no offense) is a recipe for one hot tamale.....
