Your problem will never be solved unbless you drop the tank ans either replace it or thoroughly clean it.  New carb, filter, etc will not solve your problem if you continue to try to use the dirty tank

Paul - My plan is to replace the tank, lines etc... . I will also replace the carburetor.  I want to know about the quality of current Holleys, and if any one knows of a way to filter the 18 Gallons of gas that's in the tank so that I could use it in say my lawn equipment.  If safe enough, I could use it in my cars.  I would not want to use it unfiltered in anything.

I had a 600 holley on my 272, #1......to much carb, #2......When I took the metering blocks off they were a mess, chunks of casting broke off in my hand and would basically dissolve if I ground my fingers together. Holley knew of the problem, replaced it with a 465 and right out of the box it's been a honey, I'm happy with what I got. Gary

Gary  - That's basically what mine is like.  The more it's handled, the worse it gets.

I use folded cheescloth to strain coolant if its still good after draining the radiator.  Use three or four plies.  It should get most if not all of the junk out.

Bill! If yours is like Gary's contact Holley direct.Maybe you will get another carb gratis.Worth a phone call.

  

A new 465 cfm holley should do fine after new tank is installed. I talked to holley tech the other day and they assured me their carbs are made here in the states. I certainly hope that's true!! Give them a call and ask a few questions including where their products are made. I've had good luck with their carbs.

-Gary Burnette-

A couple people recommended that I give Holey a call and see if there is anything they would do.  Well I finally got a chance to call them today.  I explained the situation to one of their Tech Service guys.  He asked for the List # and the date code.  He said that back in 2006, Holley had a problem with castings from a new vendor.  Can you believe it, the list # and Date code fall within the problem range.  He told me to pull the carb, and send it to him.  He will check it over, and if, as he suspects, it's related to the casting issue, he will send me a new carb.   
Does anybody have a good way to send a gas soaked carburetor through the mail without setting off every HAZMAT sensor between Baltimore and Bowling Green KY ?

I would power wash it,turn upside down and drain, and wrap it in several layers of decent quality clear plastic and tape it sealed in the plastic.Pack in a good strong cardboard box and completely tape with  packing tape(cover the whole thing in tape).Good thing Gary(55Vickey) mentioned getting a replacement carb for himself.May have just saved you some dinero!

  

Glad you called these guys Bill, they're not gonna cover over anything. My replacement carb was here in just a couple days, except they sent mine before I sent the bad one back, the squeaking wheel gets the grease, Gary
