Guys,

Just looking for some examples of when you have fouled your plugs. It will help us Newbie's from making the same mistakes.

Thanks in Advance.

Lots of guys just start them up when new and shut them off right away to hear the sound of the engine, and don't let them get to operating temp. When they get shut down too soon the moisture will foul the plugs. Always let them get to temp before shutting down, even if your just loading on the trailer or into the garage from the trailer.
 
Especially when the motor is cold. It's hard not to let your friends here it, but unless you are willing to let it run for about 5 minutes, then don't do it or you will foul a plug.
 
I have heard of that issue before and am very careful of that.

I was more so looking for guys actually fouling on the trail or allowing to idle too long and then fouling when you give it throttle, like a 2 stroke. I know it isn't a 2 stroke but it could theoretically happen, I think??????
 
It has been my experience......., I mean, I heard from a guy, that after casually running the machine and getting off and letting it idle, it only ran for two to three minutes until the temperature warning light came on and then the engine shut itself off right after. So idling for too long is probably not going to happen, and in this case, the plugs ran fine to this day.
 
Like every one said dont start and shut it down with out warming up and you wont have any problems.
Never fouled a plug in my viper eithor.It has 8000mi. on it with the original plugs still in it.

This is a safety feature when temps become to high from idiling the ECU gets the message and shuts the snowmobile down,Came out in 03 with the RX1.
 
Maybe a stupid question here, but why didn't any of the carbed cars I have owned, let alone efi models, foul the plugs when you just start them up cold and shut them off before warming up.

Even my carbed and efi 2 strokers would never foul a plug when started cold and shut off immediately.

I let my Vector warm up completely before shutting it down, just wondering why it seems to affect 4 stroke sleds more than any other motorized vehicle I have owned.

Do street bikes have the same problem?
