Hi everyone, I have a 1992 Polaris Indy 500 SP EFI snowmobile. I had it running earlier this year, but after about a week of leaving it sit outside, it all of the sudden lost spark. Everything works fine when i turn the key (fuel pump, etc.) but when I pull the starter rope, there is just no spark at all. I just put in brand new spark plugs, and that wasn't the case. Can anyone help me with my problem? I would greatly appreciate it.
