long story short: i recently bought a used bike on craigslist and it ran mostly fine. a little difficult to start, but tolerable. i replaced the cylinder, fuel filter, carb, and air filter in an attempt to get it running nice and reliable. now it doesn't start.
long story longer:
the bike seemed like it could use some upgrades, so i bought a new engine mounting kit, a new carb + air filter, and a new cylinder because the old one had a stud stuck in the exhaust mounting hole. now it feels like it's not sparking. i'll hold the clutch in, ride it a bit, get going a decent speed, let go, and you can hear the motor going but never actually "coughs" like it's sparking and running on its own. i've tried choking it, not choking it, using starter fluid, etc. i decided to replace the spark plug, still nothing, so i swapped ignition coils with my friend's (@colehardison35) bike (so i know it works) and still nothing. the magneto looks fine but i have no clue what i'm looking for. also, the f*cker shocks me when i let go of the clutch, so i'm pretty sure i'm getting power. i've posted pics of the magneto + how i've got the ignition coil wired up below.
any suggestions on what could be wrong? the carb is brand new, and i know it's got at least a little fuel, since i pumped that little button a ton (at first just a few times, then kept pumping because i thought maybe the new filter or the way i've got the new carb mounted wasn't doing it).
again, it literally shocks me when i let go of the clutch, so i think that means the magneto is working. also, the ignition coil is ruled out because i tried my friend's with the same result. brand new spark plug with 0.036" gap, pretty sure it's the same plug that's on my friend's working bike.
