I feel dumb for asking this but here goes. How do you remove the carb from the GRP engines? There I said it. LOL.

So I have between 1 to 1.5 gallons of fuel through my engine. I started setting a race tune in yesterday but she was running erratically. Half a lap would be absolutely perfect and the other half would be so rich the car wouldn't move at WOT. Yikes! So I decided to finally break the factory seal and seal the carb, high speed needle, and backplate. As well as grease the o-rings with some o-ring grease.

I can't remove the carb though. I removed the pinch bolt and the two aluminum carb retainers. That leaves nothing else, that I can see, to hold the carb in place. The carb will rotate just fine, but won't come out. What am I missing? Also is there a gasket or isolator between the carb body and the engine case? I was gonna try using a flat blade screw driver to help things along but this gasket/isolator was too soft and I didnt' want to tear it.
