Re: NOT TUNED

Make sure spark advance is not getting full engine vacuum at idle. If
it is, car may actually timed way too retarded (masked at idle by over
advance). Won't know it until RPM's increase and vacuum drops,
allowing ignition time to return to true setting. Could then be
shooting spark as late as ATDC.

Put a timing light on engine and watch scale as throttle plates opened
by hand.

although two of the hoses were not connected. Doubt that would cause
my D to idle fine but only go 1 mph when gas is applied. I have tried
checking the thermistor and it is connected and spark plug wires are
on in correct firing order. I just don't know what the mechanic did
to get it running this bad. I'm sure it can't be anything major but I
can't figure it out. I'll check the timing tomorrow but it idles
around 1000 RPM's now which better, but can't drive it. Any
Suggestions?
