Is this problem just when starting from hot? If so you could try a heat insulating spacer underneath the carb. Not all spacers have the same properties. There are wood and rubber based types made specifically to block heat such as the Edelbrock 9266.

Not sure about how filter with return would help assuming it's in the feed to the carb.
