For those bewildered by this post- IF you own a HT/China Girl/Flying Horse/Grubee or similar aluminum two-stroke high-strung smoke belching rattletrap parading as a motor, and for reasons known only to the deities of petrocarbon it decides to not function in spite of spark/fuel/air/compression being present, I suggest you run one more test...
Take the contraption to the top of a good sized hill with a decent road. Push off, pop the clutch once you have sufficient speed. If the engine runs untill RPM drops below mid-cruise speed, then here is the issue- the cheesy aforementioned solderjoint between coil and magneto frame has come partially undone, causing only a partial charge to reach the sparkplug- enough to fool the eye but not enough to fire the cylinder untill the magneto reaches high enough RPM. Talk about frustrating... somebody else que'd me on that, I wish I remember his name- either this site or the other one, he saved me my wits, my sanity, possibly my marriage and certainly my motorbike. Tip o' th' hat t' ye, m' boy... but here is the fruit of his wisdom, I hope it saves somebody a chunk of grief. The photos show how I resolved the issue by shaving off some insulation where the black wire crosses the solder joint and soldering it all together- as stated, I routinely perform this task before installing a chinese rattletrap on a bike. Mind you, I love the silly things well enough- but then, I've owned British sportscars and loved them as well. Same masochisem. The whole trick is learning how to solve problems as or before they occur.
I will pass on more tricks as they are brought to my attention.
