HELP PLEASE!  I have a 2006 Arctic Cat Prowler 650 H1 XT.  I got this with only 9 miles on it, and since new it is extremely hard cold starting. I am not talking cold temperature, just not warmed up.  After initial drive, it will fire up everytime.  Any suggestions?  I have upgraded to a denso sparkplug, and tried a new plug wire with a capacitor that supposedly boosts voltage for the spark. Needless to say, I am still looking for a fix.  

this may sound dumb but i have a 2007 650 H1 atv and it has a primer on the carb that i pretty much have to use in the winter, although i have no idea if the prowler is equipped with that.  

someone added the primer on your carb, prowlers doesn't come with one stock. hard starting when cold is normal for the prowler since it uses a vacuum fuel pump and when the prowler sits for a while the fuel drains back into the fuel tank and then when starting it needs to be pump back into the carburetor
