Hey guys, just wanted to add my experience here as of late.
Indianoplis, IN - picked up a shift on rainy night. We all know scoots don't do well in extreme moisture (or at least mine never has). I risked it.
Bottom line of the post is that it was the main jet and the spark plug cap if you don't care to read further.
So, got out of work and it was below freezing and wet out. Electric start would start it and it would idle die even with me giving some throttle after about 20 seconds. I kept working on getting it started via electric and kick for about 20 minutes. While doing so, and it only starting and then running for 20 seconds at a time, I wore my battery and broke the metal casting that my kick start is encased in. It had to sit for 3 days until the sun warmed it up/dried it out and I got a battery charger to the site.
After the battery was 50% charged, and it was dried out and it was above freezing - it started right up.
Finally got it home and took it apart. Main jet was clogged by about 40%, got that cleaned. (hadn't been cleaned in over a year) Gave carb a good cleaning. I had a spare spark plug and thought I should just change it out for the winter anyway. I pulled the spark plug cap off and no big deal, put my spark plug wrench in there and got plug out. On the tip of the plug was the internals of the cap.
I was able to get a generic replacement and have an oem ordered and will keep generic for emergency, but in hindsight - even when it wasn't cold out, I have had my scoot die in mid ride. I am not a mechanic and only recently started doing this stuff myself. Every time it did this was when it was raining though. So I assumed that my air filter was getting moisture and air was restricted which caused it.
Who knows, maybe it was my spark plug and cap vibrating and it caused the engine to die out.
Just wanted to share incase anyone else is having or had the same problem
Thanks for the forums
