Hi, new guy here.
I recently acquired a prebuilt bike from a guy on Craigslist. It's been working fine for a couple of weeks now. I was on my way to work yesterday and the engine choked up and stalled. It wasn't quick either, it lost power to the ground but still ran. No amount of throttle would get it back up and going. Messing with the choke made it perk back up a bit but not for more than a second or two.
I took off the exhaust and checked it for blockage, because a new drip had shown up. It was black like used engine oil, and it hadn't been there before. I removed the air filter and carb and dumped out any excess fuel, looked for dirt or blockages. There were none. I even dribbled a bit of 2cycle into the head in case I screwed up the mixture and the cylinder dried up. After I got it back together I pedaled it to start it, and it got going, but it was smoking hard, likely the extra oil I added into the cylinder. It seemed to run fine until I got to the end of my street and it started dying out again.
I'm at a loss here, as I'm not that mechanically inclined. I will admit that when I gassed up yesterday I pour it straight in and then added the oil, but there wasn't a lot of room because I was a dummy and topped off. Could even a bit of pure gas cause the engine to start seizing? Or is this something else like a clutch needing adjustment?
Remember: I'm new to these engines, treat me as such. Thanks for any and all help.
