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.

Make sure and check the belt deflection on the sled. It should be between 1 1/8 and 1 1/4. if the belt is too loose this will cause a bog on the lower end.

Hope this helps Jeff

It only bogs off of idle, once it has enough rpm's to engage the clutch it runs fine.

How many miles are on the clutching? I got a 92 Cougar with 4500 miles on it, still runs good, however the clutching is showing its age and needs a going over. No bog yet.

Sled has close to 6000 miles I probably have had it for a 1000 miles and I don't know any history on it. Might still be original motor and clutch but I doubt it. Once you get the rpm's up to 4000-4500 where the clutch engages at it runs fine and the clutchs seem to shift fine. I guess I never checked the compression. Could low comp make it act like this? It's not like I'm trying to get very top performance out of it I just want it to run good.
