What does an MGB condenser do?
What does an MGB condenser do?
Ignition Theory will explain the function of the condenser, which isn’t just to prevent points burning but significantly boosts the energy in the HT and the spark at the plugs. The reduction in points burning is merely a side-effect of putting energy into the spark instead.
How do I set the timing on my electronic distributor?
Turn the ignition key to the RUN position and return to the distributor. Turn the distributor body COUNTERCLOCKWISE until the test lamp turns OFF. Turn the distributor another 10 to 20 degrees COUNTERCLOCKWISE. Now SLOWLY turn the distributor body CLOCKWISE… SLOWLY.
How do you do a static ignition timing?
Static timing means setting the timing with the engine stopped. You set the crankshaft at the correct number of degrees before top dead centre, then adjust the distributor by turning it until the contact-breaker points are just opening.
How do you pull a distributor?
Mark the position of the distributor, by scribing lines on the flange and on the stud plate so that it can be replaced in exactly the same position. Remove the nuts and pull the unit away from its mounting. Twist it gently if it sticks, but do not try to lever it from the engine block with a screwdriver.
What is a dial back timing light?
The next level up from a basic timing light is what is called a dial-back light. These timing lights use electronics to delay the onset of the spark based on how much delay is dialed in on the light. Original dial-back lights used a simple dial with a timing scale.
Does an ignition coil need to be earthed?
The simple answer is no, the coil case does not have to be grounded for the ignition to work properly.
How do you test a coil on an MGB?
Using an ohmmeter, check the resistance between the side terminals of the coil. Do this with all of the wires to the coil disconnected. You should see 0.75 to 0.81 ohm of resistance. Then check the resistance between either side terminal and the center high tension terminal.
How do you set ignition timing without timing marks?
How to Set the Ignition Timing With No Timing Marks
- Mark the spark plug wires for the cylinder number using a short piece of masking tape on each wire.
- Rotate the engine clockwise and observe the valves on the number one cylinder.
What should static timing be set at?
I use a static timing value of 25° or 30°. Adjust the “Inductive Delay” setting to synchronize the timing advance when the engine is revved to higher RPM (momentary 4000 RPM is fine).
What’s the timing on a 1972 MGB GT?
A bit of help needed. I’ve got a 1972 MGB Gt with high compression engine number 18v…. the timing needs looking at as it hasn’t been done since the electronic ignition module was installed in the distributor, there is a slight ‘pink’ on the engine under load and occasional run-on after the engine is switched off, when hot.
What’s the correct dynamic timing for a MGB?
Road testing, as you suggest, was the best way to get that intermediate advance figure right. Typically this meant setting the 2000 RPM advance back to the bottom end of the range. On engines with the compression raised to around 9.5-10:1 then 20 at 2000 was the figure to aim for.
Where are the Ignition marks on a MGB GT?
The Top Dead Center (TDC) marks on the crank damper and the front cover must be used in conjunction with the advance feature to correctly measure the ignition timing. Reference the pictures for details on the marks.
How to adjust ignition timing on a MG?
Should your MG be fitted with a distributor that has a vernier adjusting nut, you can use this to fine adjust the timing. With the test light on, turn the nut towards R (retard) until the light goes out, then back towards A (advance) until it just lights.
