Though being familiar with the Savage (I have one since 2007), the mild explanatory pace and the soft background music ("Blackbird" nailed it) made this one a pleasure to watch. Thumbs up 🙂
I noticed you didn’t remove the 3 bolts on the side. Behind it there is a spring and rubber boot. I’m not well versed in how carburetors work, but should this be removed prior to submersing the housing to avoid the rubber deteriorating?
Was it running 'perfectly' at one time AFTER the slip on? yes/no (I assume the answer is yes obviously!) Then it sounds like a (partially) blocked Main jet. NOT the Pilot jet. Clean the Main jet. (Clean both jets while you are at it) I understand the Pilot jet's 'job' is from 0-50% throttle, and the Main jet's 'job' is from 50% to 100% throttle. Good luck.
I have the same bike my carburetor is acting up if i use a spray bottle with gas it will stay runing but every time I turn the gas on it dies do you know why
