Thanks for replying - I was thinking about putting the carb in the oven. I took off the O-ring on the bottom, the needle valve - throttle assembly - Is there any other things I cant see in the carb that would not handle the heat. When it comes out of the oven will it come loose while expanding or while its still hot do I need to put the plastic throttle assembly with a washer in between to break it loose while still hot????
