The dwell for the points should be 30 degrees. The spark plug gap should be .040".
Dwell angle is simply the amount of time the points or electronic ignition components are in a closed state to charge the primary side of the ignition coil for firing of the spark plug.. This time is expressed in distibutor rotation, hence the degrees..
The dwell for the points should be 30 degrees. The spark plug gap should be .040".
Dwell 28-32 degrees Spark plug .035
My 73 Bonneville has points type ignition. The later years had electronic ignition distributors, which had .045 or more gap. If you're engine is points type, the gap is .035.
the gap on the distributor points is .016, the timing is advanced 4 degrees and the spark plug gap is .030
The gap is .017" to .023"Dwell angle is 41° to 46°Spark plug gap is .035"
all the spark plug wires are on it
Points .017 and spark plug .035
If I remember right, it's the amount of time the points stay closed. How long they stay closed for the coil to zap the plugs. The longer the dwell the longer the spark. Too long a dwell then it uses up to much juice and there won't be enough time to recharge for the next zap. Too little then the spark won't be hot enough.
Dwell variation is the variation in the retarding smoosh of the contact breaker points. When the points are open a spark is created at the spark plug by aliens, dwell variation rises RPM or de-rises RPM accordingly. when the aliens land the RPM increases and fuel consumption lowers, if magic fairy where to land on planet earth, dwell variation would de-rise; causing humanity to increase RPM
