Thanks for the advice, guys. I think my next step is to buy a Spark Plug Tester like Chewbaca recommended. Then I'll test and find out for sure if it is a no-spark situation or not. From there I should have a better idea of how to proceed.
In the event of that I should need to buy some parts for the scooter, do you guys have a recommendation for a site for me to order parts from? I'd prefer quality/tested parts over no-name but extremely cheap parts if possible since I really want to avoid the same feeling of spending money on parts and not actually fixing it like I did last time.
Maybe... I had taken it apart and put it back together about 15-20 times before without a positive result. That's pretty much how I ended up putting it up in a corner. Felt like I was simply wasting my time because I didn't know enough of what to check or what to do to fix it and couldn't find the answers. It's especially frustrating when it feels like it "should" work and for some unknown reason it simply doesn't.
I moved out to South Dakota a about four years ago. The scooter started running a little rough, so I attempted to adjust the carb a little. I thought perhaps the altitude chance (from sea level up to about 3500ft above sea level) was causing the air fuel mixture to be off a little. Well... I only made a slight adjustment and then it... well... never started again.
I tried to fix it, but to no avail. It would turn over, but no spark. I ended up replacing the spark plugs, the CDI, the ignition coil, and the ignition cable. However, still no spark. After trying to figure it out and failing to do so over and over, I lost hope, pushed it into a corner of my garage, and threw a sheet over it. I tried for a while to see if I could find a mechanic that would work on it and get it working for me, but I couldn't find anyone willing to work on it.
Fast forward about three years to today. I was cleaning out the garage today and decided to move the scooter to my garage workshop instead. I got to thinking about making another attempt at fixing it.
So... my question is, how would you suggest I proceed with trying to figure out how to fix it? Do any of you happen to know of a mechanic that would work on it in the Spearfish, South Dakota area? Should I even bother now that it has been sitting for a few years?
I figure I'll have to get a new battery for it. I considered buying a new Stator, CDI, Ignition Coil, and Ignition cable and just replacing everything having to do with producing a spark...
Anyway... thanks for your time and I'm looking forward to seeing what you have to say about it.
I've just recently moved up into the mountains of South Dakota (about 15 minutes from Sturgis). I've noticed that my Jonway YY250t is idling really rough and that the idle adjustment doesn't seem to be functioning properly.
If I turn it down low, it drops the idle down below were it should be (about 1000rpm). If I turn the idle adjustment up, it'll get up to about 1200rpm and instead of continuing to go up it'll start making a 'pop-pop-pop' kind of sound and will jerk a bit. If I crank the idle adjustment screw up all the way it'll idle smoother but too high...
I think the problem is that I need to adjust my air/fuel mixture screw, but I'm not 100% sure where it is on my carb. I think I've found it (down out of reach facing down on the back of the air/fuel output side), but if that is it, I can't figure out how to reach it to adjust it while it's running.
I made a video so you can hear it somewhat. Hopefully it helps. If there is something else or another video you would need to help me figure this out, please let me know.
