Hello to the Group,

Over the weekend I tuned up the engine per the manual (torque head bolts, adjust valves, adjust points, timing, etc...). Truck has been running just fine; just running through the tune up process, in preparation for some longer trips.

When I first hooked the dwell meter up, it was reading 27 degrees. As I was adjusting the points to 33 degrees, the RPM of the motor started dropping at around 29 degrees. I didn't check the RPM before and after, so I do not know how much it dropped; I could just hear it (maybe 50 RPM?). The motor was not sputtering, just dropped in RPM. I revved the engine up and down several times while watching the dwell meter and it held steady on 33 degrees.

I'm not worried about it; truck still runs good. I was just curious if this is normal, or if anyone else has experienced the same? I guess I wasn't expecting the RPM to drop like it did when correcting the degrees.

Thanks in advance.
