Demon Carburetor issue

Sounds like a good plan. Make sure and spray out all the passages in the carb real good with carb cleaner and if you have an air compressor handy blow them out also. With carbs cleanliness is paramount. Also inspect it real good for any aluminum shards that may cause a problem such as blocking a passage.

Here's a little trick that helps if you have to ever take it back apart, apply a thin coating of chap stick (or any type of wax based lip balm) to all the gaskets and seals. The chap stick won't let things stick so the carb will come right back apart real easy without damaging the seals. Hope you don't have to, but just in case
