Why is my Polaris snowmobile engine not working?
That one side might be flooding out, which washes oil off the cylinder walls and lowers compression. Try putting some injection oil down the spark plug hole and pull it over a few times then repeat the compression test. If it stays low, there is an engine problem.
Why does my 600 Ves Backfire at idle?
At idle it burbles and backfires like the video shows. Coming off idle it loads up and bogs, and sometimes backfires. Carbs are clean and jetted correctly with freely moving chokes. Floats, needle and seat seem to be fine. Powervalves are clean and functioning.
Why is my spark plug not working on my Polaris?
As you get to higher RPM’s, the problem gets worse as the arcing is causing the spark plug to not fire consistently or enough. It can load up the plug and foul it.
Where is the coil located on a Polaris?
The problem is on the coil. The dual coil is mounted to a panel inside the front left fender well. There is one bolt going through the center of the coil mounting it to the panel, which mounts to the frame. The problem is not the coil, but the bolt that goes through the coil is a working chassis ground, i.e. it is the ground for the coils.
