ATC185 wont run weak spark
Hi,
I've got a ATC185 that wont run!!!!! it seems to have a weak spark, if i turn the throttle stop right in and use a brand new plug it will run (rev high) 2 mins and then die once . if it doesnt go 1st or second pull then the plug will get soo wet and no spark is then present.
Any ideas????

ATC185s wont run
Swapped out the stator coil yesterday and I have fitted new connector ends on the wires, but still the spark seems weak.
It ran again for a short time by openning the throttle stop wide open, however it then stalled once i tried to lower the tick over. Plug was wet and black and no spark was present until i cleaned the spark plug again????
Anyone had similar faults, as I am pullin my hair out with this one!!!!!

Has the bike been running fine prior to this or did you pick the bike up in this condition?
What's the ohm reading between the black wire from the stator and the bike frame?
What's the ohm reading on the primary and secondary coil?
(use this manual if you don't have access to one already)

Have you performed a compression test?
Based on the information you've given it would sound as though you're running rich. You'll want to check your carburetor and how it's tuned. Check the cir-clip is on the throttle needle. It should be on the 3rd notch. Also, your pilot screw, may want to screw it all the way in and then back it out 2 and 1/2 turn.

Hi Thanks for your comments!
I got the bike in bits about 6 months ago, but was told it has had new piston & rings and it compression tested OK. When i first bought it, it started more or less straight away and It had been starting first or second pull with a new plug althought after running it about 3 or 4 times it would not run or spark and the plug would be very wet and black.
So far Ive switched out the stator and ignition coil and changed the wiring end connectors in the hope that the spark would at least get a little stronger. but unfortunately no luck!!
I've not yet taken any ohms reading (due to mot havin a manual) thanks again!!! but hope to do so in the next couple of days.
Question: does the 185s (pull start only) generally have a a large blue spark? should a wet plug make it loose its spark as mine does?
Thanks in advance!

Just wondering what jets do you have in the carb right now? Which choke setting is it on (there are 3)? needle setting? Have you gone through it? My 185 starts with 1-2 pulls even after sitting, it has a blue/yellow spark using a ngk or champion plug (ngk=better). Another carb wont do much if it wasn't jet correct. If your switching out ignition parts with no luck time to try something different
Silly question but have you changed the plug?

Hi,
Thanks for responding I thought everyone had given up on me!
Yeah I have tried new plugs it did work a couple of times initially but soon sooted it up.
I got that fed up with is about a month ago that I decided to buy a 200s instead on ebay. Guess what 2 days after i got it home I got the same issue with this one too! . freakin sooty plugs and wont start
However, I have just bought a new carb and fitted it yesterday and it seems to be fixed...... not checked the plug yet thou, but it has started about 10 times over the last two days .
Also when i bought the carb i got such a good deal so I decided to get another for my 185. fingers crossed it will do the same job in fixing it. As the symptoms were both the same.
