i really dont know whats wrong w/ my engine, i'd replace the magneto, cdi, sparkplug,. but it doesnt help. still no spark coming out, i check the magneto using multitester and found out that magneto is good, the only problem is the cdi i really dont know how to check it .I'd remove the sparkplug and i plug it to the high tension wire from cdi to see if theres a spark bridging but i cant see, my gap is .030
the air and fuel mixture is good , is there any electrical related that i need to check aside from magneto, cdi, sparkplug, by the way i also check the killswitch its good
 
Generally speaking, if the mag is good, suspect the sparkplug and/ or sparkplug wire.
The CDI's are relatively bulletproof and more expensive to replace than a plug or wire.
BTW the wire just screws onto a metal screw inside the CDI unit.
Rule out the cheap stuff first.
 
I'd double check that the wire is screwed into the CDI and that the end of the spark plug wire is connecting with the cap. By pass the kill switch temporarily.
