Sled will idle but when accelerated, it bogs out . If I take the air intake and slightly cant it off of the air box for more air delivery, it runs much better. It has ran well previously before. I'm at a loss of why. I'm thinking to bypass the air box and put an air filter directly to the carb. Looking for answers .

Mine does this also. It seems when I have the choke on it clears the bog up but doesn't idle. I have checked the fuel pump and blew the carb out a few times

Start by cleaning the carb and jets. First

I've cleaned my carb, blew out the air , pulled the jet pilot nozzle air screw. Just drove it. Works good with the choke on but won't idle. Turn choke off it idles fine , but bogs mid range then once it gets going seems to run fine

if you've cleaned the carb / jets / float be sure to check the plunger on the choke / cold start - sometimes they stick / bind.

To me it's not getting enough fuel and with the choke on it accelerates fine without choke on it bogs.

So made a bit of headway. Jetting calls for 97.5 std size for sea level. I really figured it was lean due to the choke having to be on. So I had a 132.5 kicking around and it runs like a top. So I'm guessing I have a air leak somewhere maybe crank seal ? Thoughts? Cause according to the manual I need a 92.5 for my elevation and temp.

Hi turblue. Did your last fix resolve the issue? Just curious because i have an 05 with the exact same problem. Any advice would be greatly appreciated. Sorry for my lack of knowledge but what exactly do you mean by going to 132.5?

I did. It was a plugged passage in the carb body. I disassembled the carb and got some thin wire and cleaned every port and used carb cleaner ...blew them all and worked fine. 132.5 is the main jet.
