Trkimal High Performance Kit CDI + Ignition Coil + Magneto Coil + Spark Plug for 49cc-80cc 2-Stroke Motor Engine Motorized Bicycle Bike

So I had some issues with this, and if you do any kind of tinkering with working on things, you would understand the extreme amount of frustration while looking for a reason, it's not running right, but the diode on the spark plug that was brand new that came in with this order was loose and that's not something that you can easily see, and I literally while pulling it out and after troubleshooting, every other possible reason, I just accidentally saw the diode on the spark plug slightly move, which is clearly the reason it was misfiring, but I knew it was new and have literally multiple times troubleshot every other possible problem that could contribute to it and I find it was this new spark plug so it's a cheap part and it was extremely frustrating for a simple issue because that's not a common issue and it's a new card. It shouldn't be an issue once it's replaced new so you wouldn't think to check that while diagnosing issues you would literally check everything else before you go back and say well maybe it could be one of the new parts that came in and certainly was just that so I had to find another spark plug, which is not a common part for this that you can find on hand somewhere and I did not feel like pulling everything off, sending it back and in ordering another one it was just more of the time consuming process when you need it for a dependable ride and you have to walk in the meantime so I wasn't happy with that other than that once I change the spark plug. Everything else worked fine. It is decent ignition system, but cheap spark plug for certain.

worked very well nice increase in power and starts better
