setting dwell on dual point distributor

Yes, dwell is the rotation angle when the points are closed (connection to ground). Do you have Hydraulic or Solid Lifters? In fact, most all GM distributor caps have a little door that allows access to the points so the dwell can be adjusted while the engine is running. With a dual-point distributor, dwell time is increased to build more coil saturation and get a more potent spark. This initial distributor timing setting can vary by car but is usually from 6 to 10 degrees depending on the engine and the fuel that is used. Set dwell with the engine running with paper in between one set to 28, remove the paper and set to 32 with both sets. The wider point gap allowed it to more easily break the primary current. Could be based on distributor that one set may be slightly different from the other. I've always set the points for dwell so the coil can have max. A dwell meter is used to check the dwell angle on vehicles with a points-type ignition. Most classic cars do not have electronic distributors, but rather rely on a set of points to trigger the ignition system. To set the points gap via dwell, use an Automotive Multi-Meter with a Dwell function. If you set the point gap properly, this is not necessary, but given the nature of the task, it might be a good idea for the inexperienced to check their work with a dwell meter. For an 8 cylinder engine with dual points and a 4-lobe distributor cam, each set independently controls 4 cylinders. When the points are open, current is sent through the coil’s primary windings, creating an electric field. The longer dwell allowed the ignition to operate at higher rpm because it gave the coil more time to charge. Anywhere. Once set, this Dwell should remain constant for any RPM. Each degree of dwell=2 degrees of crankshaft timing. Brent Ackley teaches you how to time an engine for a classic car. Join us on Facebook:  Search for 'ConcoursMustang' Private group!

If you have missing heat shields or notice spark plugs lying against the exhaust manifold, you should probably replace your spark plug wires.

The location that the ignition points open is determined where the cam lobe is located with relation to the points. I hope this helps. Anytime. A standard Ford single point distributor has about 28° dwell with a .014" point gap. Mallory single points distributor has dwell of 35 degrees. The drivers side set controls “case timing” ( position of the distributor body) as timing cant be adjusted like on a chevy etc. After the dwell is set, the initial distributor timing will need to be reset using a timing light. hi, slip a match book cover in one set of points and set the other set to 30 degrees. But it seems to be sort of sparse on Ford dual point distributors. Aligning Valve Cover Gaskets With Bolt Holes, Tips for Timing the Engine of a Classic Car. That is for single point setups. The points are normally closed to produce a field in the ignition coil. The basic workings are familiar to any car buff. For a 64 427 it shows 36 dwell with a note that says "with Trans Ignition use 22-24, spring tension 21-24". Is the Intake original or has it been replaced with an aftermarket performance Intake. Most classic cars do not have electronic distributors, but rather rely on a set of points to trigger the ignition system. Use a piece of paper and put it. Mark Simpson takes a close look at how the points work and explains how they’re installed, then shows how to properly set the point gap and the dwell. Mallory Dual Points distributor has total dwell of 40 or 41 degrees (depending on which spec sheet). :thumbup: Setting Dwell: Changing the clearance in the points affects the proportion of time the points are closed ("dwell") and the charging of the coil. Page created in 0.627 seconds with 23 queries. Then block the other set and set it the same as the first one. Alternative points setting procedure: this procedure is not the best method to set points, but will work if a dwell meter is not available. A Ford dual point has 33° with a .019" gap.

It can therefore be used to check the gap on worn points with more accuracy than a feeler gauge, and can be used without removing the distributor cap and with the engine running. The easiest way to set the points, one at a time, would be to turn the engine by hand until one of the peaks of the Distributor Shaft Cam opens the points fully; pulling the spark plugs first makes this much easier to do. For an 8 cylinder engine with dual points and an 8-lobed distributor cam, one set "breaks" to fire the coil and the other set "makes" to re-energize the coil, essentially giving a longer dwell for the coil to saturate. It is a perfectly acceptable and accurate way of adjusting the points. You also eliminate the limitations of a single set of ignition points, which are point bounce and incomplete coil collapse especially at high RPM. If you don't have a remote starting loop, you can always ask a friend to be your key operator for this procedure. Added benefit in a dual point was a bit higher rpm ability, simply from a small bit higher spark current output to the plugs. The dwell of the primary set of points (first firing) should be 26-28 Degrees. The Lucas 4-cylinder distributor has dwell of 60 degrees. This is measured by blanking the secondary (or trailing) points with a small piece of card, then turning the engine over with the dwell meter connected. You may have to play with this a bit.

Learn new techniques and tips from friendly experts. Turn the wrench very carefully until you have reached the … Set up your dwell meter and hook up a remote starter. I have a distributor machine and its adapter to fit those distributors for both dwell setting and timing set, as these distributors had the ignition timing set on the machine, NOT on the engine. Many mechanics like to check the dwell measurement with an electronic meter after setting the points. They should be setup so the second set closes before the first set opens. The energy of the collapsing field is used to fire the plug. IIrc, you set the dwell on a dual point unit one set of points at a time, with a pc of paper between the other set, then opposite, if using a dwell meter. Has the Cam been changed and if so, what are its performance characteristics? contact spacing was 0.025 and the dwell at idle speed was 37-42 degrees. Very rarely do the gasket holes line up with bolt holes when you are replacing valve cover gaskets. Dwell angle is the length of time (measured by the degree of rotation of the distributor cam) the contact points open on a points-type ignition system. Block one set, I used to use a piece of match book cover in between the points and adjust the other one. Another method for setting this gap is using a meter to measure the electronic Dwell, or how long the points are closed (26 to 32 degrees for C1 V8's). now move the match book cover between the other set of points and set the second set at 30. with the match book cover removed from both sets the combined dwell with both points should be about 35 degrees. Get a multi meter with dwell being one of the measurements. Key to improved performance is increased dwell time and a stronger spark. So if you want longer dwell, stick with the original Lucas distributor. In addition, you’ll receive nine video downloads, access to GOLD member LIVE events, and so much more!
