I have a 93 cougar 440 liquid that is real boggy off of idle. If I pump the throttle or flip the choke on for a second it revs up and runs fine after that. Its done this for the last couple of years. Last year I put in new pilot jets and new needle and seat and it seemed to help a little but didn't fix it. The boots from carb to airbox are getting bad I was just wondering it that could cause the bogging or if its something else. It never bothered me when I was riding it but now it's the kids sled and he's having trouble with it. Thanks for any help.
