I ran my sled out of gas and now i can't get it to fire up. It tries to start but just won't catch. I also tried ether which made it so it wouldn't even try to fire. I am wondering if the plugs are fouled, but i don't understand why running out of gas would foul the plugs. Im also wondering if it has anything to do with the fact that i put in the 10ek plugs. I hate how long it took to change them and it is 4 degrees (f) outside. Please don't tell me that i am going to have to go back to my stock plugs because changing them out in this kind of weather would almost be impossible.
