When I go to start it, it would putter for a second then die. It would not even try when the throttle was open or the choke was even half on or the air box was connected.
When I undid the air box hose, left the throttle alone, and no choke, it would putter. For a couple seconds max. Every time I give it gas, the starter just seizes... I have no idea what would be causing this because as far as I can tell there's not even an electrical component to the throttle. Why would it interfere with the starter??
If I got it to putter, and just very barely gave it the smallest amount of throttle, a couple times it started to rev. Then I was able to open it up. It revved and wasn't even, it backfired. The carb will also shoot gas out the intake when the choke is on.
So the mikuni that I rejetted? Threw that on the hawk and it runs like a champ. Idles and pulls. I have no idea what is going on with the TBR7...
How would I go about testing something like the killswitch or the ignition coil or...? At this point, the freaking bike just won't run, while the hawk hit the ground running. I'm at a loss.
Thanks for the advice, been listening to it all.

Sounds like a serious air leak to me. If it trys to start and sputter its not electrical. Check the rubber connector from the carb to the cylinder head , it may not be on straight or the o ring is missing . you can also spray wd40 around that area while your cranking the engine. If it runs while spraying the wd40 then its leaking ( sucking air ) in that area.
Let us know
