1987-1998 big bear 350 2wd bogging down

[hunterhudgens11]

I have a big bear 350 from somewhere between 1987-1998 that I'm having some issues with. Whenever I get onto the gas quickly it bogs it down and if you don't let off it dies, even when it is warmed up. The only way it doesn't is if you slowly ease onto the gas. Could a part be bad in the carb? Has anyone else had this problem? I'm gonna include just regular pictures of it also

I’m having the exact same issue with my 1998 Big Bear 350 4x4 Special Edition. I recently got it running that way and figured it likely to be a carb issue from sitting. I re-built the carb and nothing has changed. Did you ever resolve the problem you were having with yours? Thanks.

I'd check that both the throttle butterfly and the slide were moving together and if they are right, then I'd be stripping the carb and cleaning it and checking the float level.

Other than that, check the aircleaner isn't super dirty, or the exhaust blocked.

Probably a good idea to check the charging system too..  If there's a fault with the battery or the regulator, the charging can put such a big load on the engine that they feel like they are seizing once the revs get up.
