So, got it apart, and this is what I found. I'm looking to just get a new engine at this point, and would like some feedback, if anyone has any. Scrappydog has a 200cc engine for $475.00 or a exact replacement for $399.00. Any ideas are welcomed. Attachments:

Thank you all again for all the useful information. After doing a little research I decided to go with the stock set up from scrappy's. The 59mm upgrade is not worth the 10cc/5% increase. I understand to really maximize the upgrade I would have to change the muffler, and go to a uni-air filter, and then spend a lot of time tuning. For my use, running short errands, I decided against it.
Once I get it going again, I'm thinking about selling it, and getting a Kimco, perhaps a 200cc.

Well, I decided to get some help with this en devour. I know a guy who loves taking apart and fixing small engines. I'll get all the plastics off, and let him do the tear down and rebuild. I'll show him some of the youtube videos, and pass along all the help I've received here. I'll take pics, and keep all updated on the trials and tribulations. So far, my parts list includes: 1. 59mm BBK. 99.99 2. Matching head $74.99 3. Jet for the carb. Still not sure what size I need. 4. One spark plug.  |

Thank you all for the help. The top of the plug seems to have been push down "crushed." No smoke when it went kaput. The way I adjusted the A/F was to set the idle at 2,000 rpm. Back out the Air screw till I reached max idle, it went to about 2300/2400 RPM, then turned clockwise a 1/4 turn, and then set the idle to 1500 RPM with the fuel/idle adjust screw.
With the 59mm BBK, what size jet would provide enough fuel. And on a side note, my scooter is completely stock. ie: Air filter, muffler, cdi, and so on.

Thank you for all your help. I really appreciate it! I think I'm going to go for the 59mm BBK. I'm guessing I'll need to rejet the carb? Anything else? I'll be taking it apart soon, and I'll get a better idea of what's going on.

Thank you for all your help. I was looking at the $49.00 one at scrappy's. So, what your saying is that's all I need? The scoot is not my only vehicle so I can take it slow, and do it right. I'm not sure if you read my updated post, but I was also inquiring about doing a BBK. Since I'll be in there? Or, would the kit from scrappy's be more straight forward?

ok, so can you briefly let me know what the difficulty level is to do something like that? 1-10. And what parts I need and a rough $ amount? Is this a good time to do a BBK? If I'm in there I want to make it better.

Ok, the flywheel won't spin, so I'm guessing the engine is seized. Hmm, not good I take it.

No kickstarter. That fell off when I was changing the belt, and I never could get it back on right. So, I just went and bought a good battery. Any other ways I can check it?

So, after giving my scoot a tune up, which included valve adjustment, changing fluids, and adjusting the air/fuel mixture I went for a ride. After about 2 miles of riding and at full throttle this is what happened to the spark plug. The starter turns, but it doesn't feel like it's engaging anything. Any ideas are welcomed, and appreciated. I'm not sure what to do next. This is a 150cc yy150t-12 Shenke scooter, and has 4500 trouble free miles, until now. Attachments:
