Intermittent Spark - 190cc Zip

I have no idea on what this could be, sometimes it works, others it doesn't. Any ideas on this problem guys? I have tried other plugs and it happens exactly the same.

 

190cc zip!! 2 stroke?

and possibly coil or stator

 

This be a 4t model

I have not tried the coil or stator yet, would you recommend getting a performance coil or standard?

 

for the price of it, get a performance one. i got one on my aerox, it was like £20 for standard, or £25 for performance

 

is there a real difference in them, not had a performance one before, only £18 for a zip.

 

not sure in reality, but the concept appealed to me. 18,000 volts standard, or 30,000 performance. in my head a stronger spark cant be a bad thing, especially when its that cheap

 

Thats what I thought to being I have a weak/intermittent spark.

 

might want to check your plug gap aswell, if its too big it will make a weak spark.

 

Tried doing that already with various plugs including normal and iridium ones too. Nothing unfortunately.

 

start off doing the coil then, if still no joy youl probably have to go back to the stator or possibly the cdi

 

Thanks for the tips. Will give it a try. I also cannot get it to idle and it runs very rich too. Any ideas on that.

 

on the running rich, get a smaller main jet (assuming its running rich topend)
i cant really comment on the carb without actually seeing it

 

I have an open filter standard exhaust, what roughly should my main jet be.

 

i honestly couldnt say, look whats init now and drop 2 sizes

 

Ok thanks, also the idle screw makes no difference when I turn it.

 

sure its the idle screw not the mixture screw?

 

also, does it have a regular tickover or does it change?
