I just picked up a 110cc 152fmh and it has no spark, but I know what your going to say "ignition coil " I have ordered one it will be here in a few days and can't wait. My question is how can I test other components while I wait on my coil. Stator, source coil, cdi, and rectifier. I believe that the cdi is ok used multimeter on it but not sure i know what i'm looking at. I will post pics soon to better explain. thanks

Do some carb clenaning, valve adjustment, cleaning and lubricating chain, while you wait. In any case, these jobs would be waiting for you after coil installing.
Spec from CDI maker: http://www.sanxin.com.cn/info5/index.asp?id=12
Other parts can use http://www.dansmc.com/electricaltesting.htm as a general guidance.
Carb is already soaking, going to do oil change and chain tomarrow. BUT I think the coil isn't the problem!!!!! I checked the ignition coil with multimeter and I think it is good.

I opened stator cover and water came out.:frump:

So I polished out the rust, and thie pick up spots then checked with multimeter;

The only one I didn't get a reading on the part i think is called the exciter coil.
Is this part bad? Sorry first time using multimeter. I also checked blue/white wire to CDI for breaks it was ok.
It's the older type!!! the newer one (http://s.taobao.com/search?q=%8F%9D%...obaoz_20120806) is compatible with GY6

Direct swap: http://item.taobao.com/item.htm?id=10836206479 fleabay is ~$19.99
Upgrades for the older type.
ALL DC (ie. no source coil) -DC CDI needed http://item.taobao.com/item.htm?id=4435967033
The 90W 3+1 http://item.taobao.com/item.htm?id=14804910536
A man can always learn something new. This is the first time I saw 3+1 coil for horizontal engines.
Thanks, Humanbeing! :thumbsup:
Not to forget: according to the manual I have for horizontal engines, the primary coil resistance should be between 0,1 to 1 Ohm, and the secondary, with the spark plug cap - 7000-9000 ohm, and without spark plug cap - 3000-4000 ohm.
So Arlie, if manual deceived me, I deceived you.

The odd things seem to find me.:l

Strange or not, this thing produce 90W!Quote:

Thanks. :thumbsup:
New stator didnt help! Stator is identical to stock. HOW do I know if CDI is AC or DC. CDI is smaller 5 pin squarer single connector.Attachment 8203Attachment 8200Attachment 8201Attachment 8202:confused1:
U get at least 1?v if kick start repeatably from source coil ie the "ext" http://www.sanxin.com.cn/Exhibit/exhview.asp?pid=3
AC if it's small. You can also trace wiring if it's using a DC (Got the juice after "rectifier")
the gap btw Pulse coil & rotor is also important to tell the CDI when to make a spark.

:confused1:
I would be surprised if it turns out that there is a separate coil for AC or DC CDI.
The so called chinese "generic" DC-CDI uses SAME ignition coil as AC-CDI. (电容 type)
The (电感 type) is different animal. For example: Suzuki 125 or the those hi-end "upgrade"
Translate these get the basic idea: http://www.motorfans.com.cn/bbs/t_17374516_1.htm | http://www.sanxin.com.cn/Exhibit/exhview.asp?pid=62
I have spark :clap: . A previous owner had a DC CDI installed, and it was fried. Replaced with AC CDI, and spark is good. Good enough to zap me :lol8:. Thanks for the help. Still more to do see you next post.
I'm in good shape now running okay but valves are noisy. So I would like to check the valve clearance but need the feeler gauge sizes. What is the intake clearance and the exhaust clearance? thanksAttachment 13141Attachment 13142
