Fouled Plugs

[CoreyYoungCj577]

So alot of you guys help me out alot and i appreciate it Thank You!

So i got bored and i knew the #1 plug was fouled, so i decided to change it along with #2 one also, well then i decided to pull the third one just to see what it was like, and guess what it was fouled! The engine is the AMC 258 i6 / 4.2l straight six with the three speed Transmission in a 77 CJ7 that sat for ten years. I'm attempting to bring her back to life.(its all stock)

So then i decided to come up here and ask all you great fellow jeepers what would cause a engine to foul all plugs, i didnt go further then third, assuming the rest are fouled.

Thanks guys!

The first 3 plugs i pulled and assuming the rest are Carbon coated which is

fuel fouled. What would cause it to foul all 6?

Carb running to rich. Thats probally why it' was running like .(missing) could be a stuck float or dirt under a needle making it dump to much fuel. A carb rebuild might be in your future.

X2 on that, even a dirty air filter, old worn out plug wires or cap & rotor can cause it to carbon up.

I would much rather have all six foul than one or two. I thought you just replaced the plugs rotor wires and cap. did you clean out the fuel tank?? a spray can of carb cleaner could take you a long way.

I did do all that except i didnt clean the fuel tank and it has alot of gas in it now ha but the plus is i have tools i took off the hood tonight. Going to take all the seats out and tear the carpetting off tomorrow. Then maybe if im feel strong attempting the body tub= EASY access gas tank woo!
