Hello There,
I have a Bayou 300 that run's fine can run for a few hours ou a few minutes....then the thing dies and the only way to bring it back to life is to change the spark plug I just rotate them put back the old one and I will run again.
It's a pain and would like to know if this could be fixed but don't where to start looking
Thanks for your help

 

How does the plug look? Can you tell whether too lean or too rich? When it dies, does it gradually die or suddenly like a kill switch?

 

I think the mixture is good when I do remove the plug it's a bit oily on the black side.
And when it dies it's like a kill switch.

 

Bad ignition coil can heat up and open short, causing no spark condition. While you replacing the plug, the coil cools down and becomes good (temporarily). So you would think, replacing plug is fixing the problem. Just my 2 cents.

 

Thanks will change that and keep you poasted
