timing
I wanted some advice on where to set the timing. I have a 90 302 and the label under the hood says to set it at 10btdc. I have heard that if you advance it farther it will run better. Is this true, because I would like to get all that I can out of it.
I have heard that if you advance it too far you will hear a pinging. Today I adjusted it and was just moving it around to see what it would do.I took it up to 25btdc and never heard this pinging. Maybe I don't know what to listen for. What does this pinging sound like?
So I ended up setting it at 12btdc. And, yes I disconected the SPOUTwhen I did it.
Just out of curiousity I plugged the SPOUT back in and checked the timing. The computer had adjusted it to 20btdc. And when I reved the engine up to 2,000rpms it jumped up to 30btdc. Does all of this seem right?
Also, do you have to have the engine at a certain rpm when you set the timing?
Thanks Everyone.

all of that sounds right, the engine needs to be idle speed when you set the timing, but you will never hear any ping (sparknock) while its idleing, you will hear it going up the road, it will sound like the valves rattling hope this helps DW
