Timing issue?

So... When the choke is closed (cold engine) the engine runs fine, when the choke is open (engine warms up) it doesn't.

Except for the rear float issue, sounds like a vacuum leak to me.


not sure what i have to do to fix the issue of the rear float sight glass filling up to full other than take a new carb apart which i shouldnt have to if summit got things right it should be fine id say maybe i need to contact them about the issue bc the float screw is maxed out that pushed the float level down . that trick worked fine on the primary bowl it brought it down middle level of sight glass
