I'm currently running this engine and I've seen that people recommend wwapping out the chinese spark plug with an NGK B6HS. Well I attempted to order one the other night after having a few drinks and I accidentally ordered a BP6HS. I realize that the P refers to a projected insulator, and after a little research people actually like utilizing them in their MB's. Prior to riding I made sure to turn the engine over by hand to ensure that the piston wasn't hitting the spark plug. It didn't seem to be, no real noticeable damage to the spark plug. I tried running it today though, and it would never actually get up and go. The engine just kind of lugged like it does when I'm first getting it started. Tested it with various choke positions, damn near identical outcome. I ended up letting the engine cool-down, took it out and took some pics of it. Seems to have some oil on it. Does this mean that it's running too rich and I need to adjust the carb?
Also, once the engine cooled down, I put in the original plug to isolate the issue and it ran just like it was when I was still using the original plug. Took it around the block and was it's normal old buzzing around self.
Lastly, I mentioned this in my last thread, my bike only runs when the choke is all the in the down position. If I lift it up, it will quickly die out. I'm assuming this is demonstrating a need to adjust the carb as well, correct?
