Default Re: Oil-Gas ratios

A fouled plug is one that is covered in oil and created a weak spark or no spark at all. When your plug is fouled the engine will be hard to start and will run like crap, especially at lower RPM, sometimes running the engine really hard will burn off the plug and it'll start working well again.

If running it hard dosn't work, remove the plug and you'll notice that it's black an oily and will need to be cleaned or replaced.
