Hi all,
I have a question about why my 49cc TGB r50x scooter wont start. I tried to start 'er up after the winter, remembering that in November she wouldn't start, and not knowing then either what was the cause. The old problem had been that, (1) the scooter never would start via the ignition key, and (2) it used to be starting fine via kick start, but that by November it wasnt working that way either. As a noob, I tried looking through the forum and manuals, mainly getting frustrated by what I did not know.
Now, after the winter, I noticed the problem was even worse. When I tried to start via ignition, the engine turned over VERY slowly, and then not at all. I noticed that the battery just kept losing its charge even though I kept also plugging it into the trickle charger. So, I replaced the battery. After doing that, I noticed that the fuse had burned out (probably because of the installing of new battery?), so I went ahead and replaced that as well. This made a noticeable difference -- when I turned the key the engine properly turned over at full speed, no lagging or sluggishness. But alas, no start.
I did manage to start the scooter via kick start, after maybe the third try, and kept 'er running for a good five minutes, revving and idling, and checking my air/fuel screw to make sure it wasn't completely out of whack. I then took 'er for a ten-minute drive, but when I got back and tried to kick start again, no luck at all, even after several tries. Thinking I might have flooded the engine, I waited for 10 minutes or so, then tried, and still nothing.
So, I feel a hunch that some part of the electrical chain of command before the spark, is to blame. I also suspect that there might be a SEPARATE issue only to do with the ignition start, as I spent all summer last year, my first months with this second-hand scooter, being able to start it by kick start but NOT with the ignition key.
Anyway, I'd love to hear suggestions on what you think I should try next. Feel free to ask me whatever questions you want to help me diagnose my issue. One thing I'm going to do is follow the helpful prompts from 90GTVert, listed here: 49ccscoot.proboards.com/thread/647/start-troubleshooting?page=1&scrollTo=8057. My goal is to start from "section 8," titled "turns over but won't start," and do each check outlined there.
It starts with checking the spark plug, some thing I have never done because I still haven't figured out how to get a socket wrench with an attachment that can reach the bolt around the plug, which is deeply recessed inside some black plastic housing at the front of the motor. So... if anyone has tips on HOW I can get in deep to get a spark plug bolt untightened, I would love to hear it!
