So i have a CG125, One day it was fine, Put it away, GOt it out about 2-3 weeks later, Wouldn't start, Had a ifddle with it and found out there appears to be no spark, Will do more tests on the spark tomorrow.

Battery is fine, Fuse is fine, I'm thinking it could be the HT Lead or the Coil?, If so how would i check either one?, i'm no mechanic, Please help!

Have you changed the spark plug?

Unscrew the spark plug cap off the ht lead and put it somewhere near the frame/engine and see if you get an electrical arc.

use an electrical tester and see if there is a pulse to the coil, earth one lead of the tester to the frame and touch the other to the input terminal of the coil, turn the engine over and you should get a pulse signal, if you do its the coil, if you dont its at the cdi OR points area.

Yeah it's a brand new plug, I've tried testing it like you said and there is no spark
"input terminal of the coil", Would i need to take the Tank off to get to this?, I think it's hidden under the tank., If it's the CDI what does this mean?
