If the magneto is not working then you will notice it down on power (you can test this by removing the wire from the magneto at the key and connecting a 12-18 volt cordless drill battery to that point on the key switch and switch it from 6 to the 12-18 on the move, Should speed up a lot. This will tell you the coils might need some adjustment.)
CRC sounds hopeless on a timer but it doesn't sound like the problem.
You may want to blow air through the fuel line into the fuel tank while you're tinkering with it if its doing that surge thing at speed.
