It’s all fun til the rabbit gets the gun.
I recently bought 3 new 2300 carbs. I had to replace the rear carb’s center hung bowl with a side hung bowl. I used the center hung bowl’s needle and seat, bought a new side hung float, tapped and plugged the outside fuel hole that would typically go from primary to secondary bowl (for single inlet carbs), and it will not stop overfilling the bowl. It runs for 10 seconds until the bowl is completely full then floods and cuts off. Remove the sight screw and fuel flows out heavily. Pinch off it’s fuel line and it purrs forever. I’ve adjusted the float level, bent the float so the needle would close even sooner, still over fills. There was some debris in it from tapping the hole, removed it but that wasn’t the problem. Does the side hung bowl have a different needle and seat than a center hung?? Open for suggestions.
