05 rev 800 starting issue

[skidooklimer]

So my 05 Rev is getting spark,getting fuel,has good compression but will not fire..the tach doesnt even try to light up or move the needle when I pull the chord.Anybody got any ideas?Any help is greatly appreciated

motors need 4 things: compression, fuel, spark, and timing. if your certain the others exist (are you sure the spark is good enough? or is there enough fuel?) then it has to be timing. pour a bit of fuel straight in the cylinder through the spark plug hole and see if it fires.

If it's electric start it has to have a hot battery to start...

Why is this? Seems odd if he is getting spark it should fire....
