SOURCE: put new engine in carnt get a spark at plug sym

There may be several things causing this fault (your sure the plug is fine?)

The ignition systems on these bikes are pretty basic. The Stator plate provides power to the CDI unit, which builds up until the pulser tells it to send the power to the coil and produce the spark

1. is there voltage from the stator plate (under flywheel) - you can test with a basic multimeter.

2. is the pulser sending a pulse - also can be tested with basic multimeter

3. is the CDI blown? - swap out to test

4. Is the Coil blown? - can be tested with multimeter

it is also very possible that you may have got a couple of wires mixed up when you switched engines.

SOURCE: My SYM EuroMX 125 won't start. Starter motor doesn't turn.

Check the wiring for a loose connector. Check grounding. The click is most likely the solenoid that is supposed to connect the high amperage to the starter motor.
Starter motor needs replaced
Wiring batt> starter came apart/ worn through insul.
so electricity not getting to starter.
Engine locked up - starter can't turn it (bad news)

Call the dealer or mfr about a service manual, or look up clymer books (publications?). Meantime, goto library reference section 646
