My 340 getting 6 mpg

I think the carburetor is to be replaced with a brawler or std holley 3310.
Someone's been into it. Ootb it's supposed to be 71/82. Bleeds have been fiddled and the jets were 65/75, could correct it.. but the plate is **** and it's not a good look so far.
I agree. I decided on the holley brawler 680 vacuum secondary.

The plate i have now is ****. I dont recommened FST carbs to anybody lol
