In the beginning of fall, I completely rebuilt my quad, and it wqas running great after i got all of the kinks worked out. Now that it's been getting colder, it's been extremely hard to start. I still have spark, and what fels like good compression, but in order to get it started, I have to have my dad pull me around the football field in back two or three times, and then it starts. It takes about a minute or two to get it warmed up, but when it's warm, it runs fine. If I shut it off and start it again, it will start right up. If I let it sit for about 15 minutes, than it won't start again. Do I need to change the jetting due to the cold weather. I've got the biggest jet that my kit came with, and the biggest pilot jet. My plugs are coming out brownish black, pretty close to what they are supposed to be. Could somebody please help, because this is really irritating me. Thanks
