Final Update: Well dont I feel like a total idiot. During this whole process, when we had taken the oil injsction pump out. Mixed are own gas and oil, we replaced the carb boots to the block with new ones....well we think that the heat from that application then caused those to heat up and warp. Well after carbs being cleaned, same problem then we looked after setting carbs back to factory setting. Those boots were not making a complete seal. The only time it would idle is when you had choke half way on.....well put old boots back on and guess what idled like a champ....up and running like my hair is on fire now. Thanks for all the help. Look forward to trying to help out others down the road on Cougar 550 Arctic Cat rebuilds or issues.....I will personally say that this was a great learning time. What fun we had doing this along with large amounts of profane words and a large amount of adult beverages consumed.....Thanks again and happy sledded'
