Here's a video of the issue:
So I'm a Carb Noob. I can adjust mixture screws, idle speed and rebuild them... But that's about as far as it goes. I rebuilt this carb when I restored this daily driver 3 years ago. If this were my snowblower I'd just rebuild the carb again. Is that my only option?
Is there something I can do besides just pull the carb and rebuild it again. Adjusting mixture screws doesn't have any affect. Increasing idle speed helps, but the idle speed ends up being way to high for regular operation.
Runs smooth as soon as I add some throttle, but back to idle and it throbs again.
Thanks for any help from you carb gurus.
