Lightbulb 4af carb. vapor lock problem

hi guys.. about my 4af carb.. i figured it out it has a vapor lock..

when i turn off the engine when hot.. its flood.
when i first encounter this problem i dont know what to do. i remember when my mother used the car and the idle drop and the engine dies unfortunately the car still got home.. and when i open the hood i smell gas and i take off the air filter and look down the barrel and theres boiling inside the carb and the fuel continuously flow throw the barrel..

so i deiced to put a heat shield to the fuel line and fuel pump.. a aluminum foil tape i put a lot to reduce heat.. and i adjust the float a litter lower..

i hope it work.. what else can i do?.. put some thermal wrap at headers?

Theres really not much to do there. Wrapping the headers thats on the other side of the engine wont really help.
