[DML] Re: HELP ME

To check the mechanical advance disconnect the hose to the vacuum
advance. Start the motor and check the timing. Now as you increase the
speed of the motor you should see the spark advance. If it does then
the mechanical advance is working. You can get more scientific about
this and actually measure the amount at the different RPM's. Most of
the time if it moves at all it will be OK. To check the vacuum advance
just hook it back up back up but remember to deduct the mechanical
advance. Together they equal "total advance". Before going for the
fuel distributer I would have the fuel injectors cleaned and tested.
