Orange Spark

whitney1207 · 05-11-2014, 09:08 PM

So I've been having nothing but problems with my 50cc taotao.

I rebuilt the carb and replaced the jets and got it running. Then it died on my coming home from work.

I took the spark plug out and check the spark it was ORANGE... I thought it was supposed to be a blue spark?

Anyone familiar with this problem?

sounds like you need a coil

Hi
I would try a new plug first but it does indeed sound like your coil is not putting out what should
Take care and ride safely

A friend at work said put a capful of gas in the cylinder and if it starts, its a fuel problem, if it doesn't, it's a spark problem..

Can anyone confirm this?

Damn! I just put some fuel in my cylinder and it started for a minute. SO I took the seat off and noticed that there is no fuel in the NEW fuel filter I just put in...

I got the smallest fuel filter that they had at autozone ... do you have to get the smaller scooter one for a 50cc.. it's definitely not flowing through the filter

HELP

Its not the fault of the filter that fuel is not flowing. Have you checked the petcock?

Even something like a kinked line...

try starting it with the fuel line off.if no fuel comes out you probably have a bad fuel pump,(petcock)

I took the line off the fuel filter output (to petcock) and it still didn't flow. I took the line off the filter input (from gastank) and there was fuel there. I just don't understand, I just replaced the petcock and filter. The ONLY thing is it's a little bigger than the old one that was on there. I even took the vacuum line off the intake manifold and sucked on it to see if I could get it flowing....

maybe the gas tank's not venting.. I woke up this morning and now there's fuel in the filter. I'm gonna get a new one just in case and drain some of the fuel and cut some of the rubber gasket off the gas tank cap.

I would try to remove the cap while it's low on fuel and see how it runs for a short run if the filter has fuel flowing then it's a vent issue and if it vents through the cap that might where the problem is. cutting a gasket could spill fuel all over while riding.
