What causes ignition points to burn?
The usual causes for pitted or burned points are setting the points too close or having a bad condenser. I assume you have replaced both the condenser and the points, so double check the gap on the points. Or even better, use a dwell meter if you can find one.
How are timing points determined on a scooter?
All timing points are given by degrees before top dead center or BTDC. Have a look at the model pages (Lambretta)(Vespa) and determine how many degrees BTDC is required for your scooter make and model.
What’s the best way to set the ignition timing?
Setting the timing dynamically is recommended once you have fitted one of our electronic kits. We can offer strobe timing lights that are very easy to use. There is no easy way to see or hear when the black trigger is in the firing position with the red module that compares with the contact points just opening.
Where is the timing alignment pin on a powerspark ignition?
The marks are shown below “The timing Alignment pin” is the pointer on the engine and the white marks 5 TDC 5 10 15 etc are on the pulley. So looking below at the photograph (remember the pulley rotates clockwise so it’s gone past the timing alignment pin 10 and 5 and you can see the setting is between 5 and TDC ) say 2 degrees.
When do you set the dwell on a point engine?
You read above that the ignition timing is the last thing to set when tuning the engine. Your dwell, and thus your points gap, needs to be set before you get out the timing light. To set the dwell, remove the distributor cap and rotor, ground the coil wire and remove all the spark plugs from the engine.

How do you set the points on a motorcycle?
Start with cylinder 1-4 for a 4 cylinder motorcycle. Remove the points cover. Start the engine. Aim the timing light through the points plate view hole. Confirm that the “F” mark aligns with the engine case’s timing mark at idle. Rev the engine to about 3,000 RPMs and confirm the parallel advance marks line up with the motorcycle’s timing mark.
What happens when you set the ignition timing?
When you set your ignition timing, you’ll either retard or advance the spark. In general, low compression engines will need more of a spark advance than a high compression engine. As engines wear, they loose compression overtime, which is why it is important to regularly check and time your ignition to keep your engine in top shape.
How do you set the timing on a Honda Accord?
Turn the key ON and crank the engine. Using a feeler gauge to get close, adjust the points to the desired setting according to dwell readings and tighten the points. Crank it again to be sure the dwell angle is still correct. You can now go on to set your timing.
