Lost spark

Cart ran motor was week bored motor ported intake & exaust ports Fly cut

head built custom exaust replaced igniter- coil- spark plug-ignition switch and seiolinoid still no spark any body got any clue?

As far as your no spark issue goes, as long as everything is gapped properly you can refer to this thread for the only other thing it could be

If you're still not getting a spark and it's not the RPM limiter causing the issue, you'll need to test the coil and ignitor because aftermarket parts, especially those bought from Amazon, often don’t meet the same quality standards as OEM parts. Let me break down why and what you should look out for.

The ignition coil transforms the battery's low voltage to the thousands of volts needed to create a spark in the spark plug. The ignitor, on the other hand, acts as a switch that turns the coil's primary current on and off. If either of these components fails, or the RPM limiter, your engine won’t get the spark it needs to start.

Aftermarket coils and ignitors often suffer from inferior materials and construction. For example, the winding in a coil might use lower grade copper that doesn't conduct as well or insulate properly. This can lead to overheating and premature failure. Similarly, the ignitor might use cheaper transistors that are not as reliable under high heat and electrical loads. These components are often prone to failure because they can't handle the stress of regular use.

Some of these aftermarket parts might even be defective right out of the box. Manufacturing inconsistencies mean that quality control can be lacking. The insulation on the coil windings could be too thin, causing internal shorts. The semiconductors in the ignitor might not be able to switch the high currents properly, leading to no spark or a weak spark.

Because of these potential issues, we need to use a multimeter to test the resistance of the coil and the functionality of the ignitor before installation. Testing can reveal whether these parts are up to spec and functioning as they should. If you find they are not, it's often worth investing in OEM parts or trusted aftermarket brands known for their reliability. If you have any questions feel free to ask!
