How are your plugs?

 

plug are ok i think. it runs good when you get it started. thanks jp

 

How cold is it getting where you are?

 

x2 how cold is your area? If its below zero you may want a block heater.

 

Yeah, that's what I was getting at. Where I am it gets to be as low as -50 Celcius (-58 F), and if I don't plug it in overnight you can pretty much count on it not starting the next day. With a block heater it fires up no problem though.
