Sled not running right

[Grimm]

Is the sled turning over? Are the ignition coil boots firmly installed onto the sparkplug terminals? With the new sparkplugs, did they have the caps on the terminals? Because they are not supposed to. Are the ignition wires clicked in?

It was running fine then I parked it and then it ran on 2 cyl,so im sure its gas. everything is plugged in tight,i am not 100% sure about the caps I think they did

Maybe there's a loose nut behind the steering post?

I was thinking that too, but I'm leaning toward the Johnson rod rotational alignment.

So you changed the gas then you parked it and now it wont run right again?

I am just going to do what I said,I am sure it will work. If it does not I will come on here and see if you guys can figure it out

ok guys new gas with sea foam,I took the plugs out they were black,I put a lighter to them because the roads are kinda bad and dont wanna drive out there. Now it wont run,it back fires when u start it and when it finally did start it ran for like 30 secs all messed up and then shut off. would could be the problem?

Once the roads are clear i would get a new set of plugs and see if the new gas sea foam and new plugs cures the problems. It probably will.

The plugs were jet black what does that mean?

 

[yamahas]

It is carbon deposits. Not all the fuel is being ignited. Could be the pulgs got fouled. If gas was stale it would not burn very well causing this too (I think). Time to change em

So black meams the plugs are shot?

 

[yamahas]

yup, maybe post a picture so we can all see how bad they look and help further.

it is now flashing 33 and the motor light came on flashing,but it wasn't running when it did that i just tried to start it.

 

[yamahas]

Did you forget to plug the coil back in when you took the plugs out?

 

[2008 Nytro RTX]

is that what it means?
