Carb problems

[Tiresmoking]

Had a problem on my 84 venture where gas was pouring out of the bowl. So I filled the carb bowl up with carb cleaner.

Drained it and fired it up and # 1 cylinder will backfire out the carb till it’s warmed up. I pulled the diaphragm out and it was separated from the slide. Put it back together and it still does it. Think the carb is still dirty or just out of sync with the rest. Like I said when it warms up it seams like it runs fine.
