Just got it firing!
I'll tell the whole story, I bought a new old bike, MG 850t, then my friend came over and noticed that it wasn't firing on one cylinder. so I tested the spark plug on that side and noticed that it did not spark, I figured I'd buy new resistor cables and resistor for the spark plugs. installed them, no dice during test. so I sanded down the surface of all the ignition points, adjusted them, and I tested the coil and it was fine too.
it was a that point that I realized that I had been testing the plugs incorrectly, not allowing them a ground. as soon as I tested it with a ground it sparked beautifully. So now I don't know if it's been okay this whole time or wether I fixed it, because now the bike will not start whatsoever. I get a few thumps when trying to start after waiting a while, but nothing more.
I check the plugs after trying to start and they're wet with gas (I think), so I test the plugs when wet, and no spark. I'm not sure where the presumed fuel problem came from, but now I'm in a pickle. I've got the idle mixture set at stock, even though the exhaust is straight pipes with baffle, but I've fiddled with the idle screw and can't find what the stock amount of turns outward it was/is. even still the plugs are wet upon start. I could use some help, this is my first time diagnosing a no start/no spark situation.
