I have never had trouble starting it until yesterday afternoon and this morning. I eventually got it to fire yesterday, but this morning I had to open the airbox and use starter fluid. Once it starts it runs like a champ and restarts on the first turn of the starter once warm. Any ideas?
Just changed the sparkplugs a week ago.
I would think the injectors are fine since it runs well once started.
Gas in the tank is about 3 days old.
How old is the battery?
Brand new. Just replaced it last week with the sparkplugs. The starter is turning the motor over plenty fast.
And when I say cold...the ambient temperature is 65 - 70F...so not extreme temps or anything.
