I would first make SURE you're not getting spark. It's hard for me to hold the plug on a bare spot on the jug with one hand, and kick it over at the same time. Have someone hold the plug on a good ground while you kick it hard.
If you're not getting spark, then it is SO MUCH EASIER to have some known good
parts to swap.
These are the things you need to maintain for a good spark on a two stroke:
Coil (make sure the contacts are rust and corrosion free)
Stator assembly (Check the connectors for mud, rust, corrosion etc. and clean the stator mounting area)
Spark plug wire and boot (unscrew the boot and make sure it's not corroded.)
Switch. (The switch can corrode and lose contact. frustrating)
Spark plug (Do your testing with a new plug)
CDI ( usually when they die, they die. Get one or two from ebay...you may need it if you plan to keep the trike for any amount of time)
In my experience, testing these components via multimeter etc. does not work. Having known good
parts on hand that can be swapped is the easiest and least frustrating.
I have a spare coil and CDI you can use for testing purposes but need them back.
