HS = http://www.hensim.com/ Their VIN starts w/ LUA
OHV / OHC can distinguish easily by urself. http://www.motorfans.com.cn/bbs/viewthread.php?tid=180

Re: GY200 is whipping me.
"I wonder if my HS 163FML 200cc engine is a pushrod type engine. It doesn't have any ports on the top of the engine for adjusting valve clearance"
It's a push rod engine based on the CG125 Honda engine.

"I can't even get it to crank anymore."
Do you mean that the engine will not turn over when you push the starter button? Did you accidentally turn on the kill switch? What happens when you use the kick starter?

Heh heh ... that was my first thought, also, speaking from experience. But he says he gets a spark, and I think the kill switch eliminates spark. Or does it? I always thought that was how it worked, but have actually never checked.
Otherwise, if there is absolutely NO cough, sputter, attempt to fire ... not even once ... then it is either spark or fuel mixture. But if fuel delivery seems ok, air delivery is ok, and if spark seems ok ... then it is very strange that it won't even cough once. And yes, as barnone asks, what happens on a kick?
My hunch is that it has to be spark. I recall an electrical gremlin I once had with a Honda - if the battery was weak, it somehow changed my spark's initial firing time and no matter what I did, the bike would never cough. I have no idea what goes on inside those little CI black boxes that have replaced the old-style ignitions. Anyways, a full battery charge immediately fixed the problem, although it recurred each time I let the bike sit (and the battery drained a bit). But doing a trial and error of replacing electrical components is very expensive (plug, then plug wire, then black box, then battery, etc).
Yup, you need the wiring diagram with specs and a good volt/amp/ohm meter. And a case of beer.
Re: GY200 is whipping me.
Thanks for responding
humanbeing and barnone, with your help it does look like it is a pushrod type engine. On the CG125 website, are all the tuneup and valve clearance data accurate for the 200GY, namely valve clearance 0.08mm (0.003 in)
I dug out my certificate of origin and it says it is
Manufacturer: Chongqing Huansong Industries
Make: Hsun
Model: MDL-200GY
VIN starts with LWG
Funny, I went back to the Powersportmax website and it appears they have removed all 200cc motorcycles and above. They still have a few small pitbikes.
Sorry MJH, I knew it was ridiculously long. I deserve the jab.
Since mine is all apart a found a web photo of a crashed MDL-200GY that looks identical to mine.

Re: GY200 is whipping me.
Here is the followup on what solved the problem.
After tracing all the wiring, repairing the shorted (sparking) wire, checking the carb, and watching the constant weak spark, I decided to buy a new CDI and Coil. It would not cough or sputter. So in searching for places to purchase a CDI I found several internet sources for anywhere from $15 to $60. Then I stumbled into Roketapartsonline.com and they sell the CDI for only $3.95. The coil was only $9.95. So I paid the exorbitant 2-3 day shipping and the whole order was still only $29.85.
I ran out and plugged the new CDI in, turned the key on and pushed the starter button. Presto! It instantly roared to life. Sounds so awesome and smooth. While I had the carb apart I moved the E clip to get a better idle and It instantly idled better than it has idled before. I now have a spare coil and I will probably order another CDI and just keep it on the shelf, just in case. At that price why not.
It was the constant spark that was throwing me off. Weak spark is a bad thing on this engine.
Thank you for all the help MCM
Now lets get to riding :clap:
Re: GY200 is whipping me.
What would be the best CDI for that engine, I am now stuck on DC apposed to AC.
CDI seems to be notorious for failing, is there a better version CDI and can it be purchased direct from CHINA?
Maybe this one….we need the expert…are you reading today 尊敬的专家.

Re: GY200 is whipping me.
DonS,
Glad you are back in business.
"It was the constant spark that was throwing me off. Weak spark is a bad thing on this engine."
What does the spark look like now as compared to the weak spark?
Which CDI did you get from Roketapartsonline.com?
Thanks,
Re: GY200 is whipping me.
MJH - The CDI I got was a DC unit. I called to ask advise and was told that the DC was by far the most common one that they supply. Very few have needed the AC units. In fact they only carried the DC units until recently when they had a slight demand for AC units. They are currently out of AC CDI's because they order so few of them.
here is the link to the DC CDI
