Clogged carburators

[1992offshore]

I need help, my 1992 offshore was starting ( I have not used in 7 years ), I was using a remote tank until I drain the 30 gallons I had in the tank.
Long story short, i filled the tank with 40 gallons of new gas and a can of seafoam, last thursday I was ready to water test her and we decided to turn her on one more time before heading to the marina.
And she refused, so I remove the fuel filter and all I saw was this red liquid and I mean red..... Let me be frank, my told told me to drain some gas before trying to start her and I said no......big mistake.
We removed one on the hoses and pump enough until we got good gas.
End result 4 clogged carburators, I filled all the lines with clean gas for 2 days, did not work. I have blown air into the gas lines with small compressor, did not work.
Engine turns on great when I spray gas into the carburators.
I am ready to really blast them with heavy air, but I dont know how damaging can that get.
Any idea are welcome and I mean any, I dont want to spend 1000 plus dollars to have them rebuilt.
Thank you in advance from Miami.

One more question, what can I spray and where that might help.
Thanks again

Re: Clogged carburators

So the motor runs on the remote tank, not on the regular tank? If so pump the tank empty, mix it 50% with new gas and use it in your lawn mower. Doesn't run on remote, clean your carbs making sure floats and needles are working.

Re: Clogged carburators

Sounds like you are saying the carbs set for years with gas in them.........If so, the carbs are gummed/varnished up, only proper way to repair is to remove and dis assemble and really clean the internals of the carbs

Sorry guys I have been working late every night this week,

The motor was running great with the remote tank, that is how I got to run after 7 years, the problem began after I drained the old gas from my pemanent tank and filled it up with new was and I added a can of sea foam.,

I supposed seafoam diluted everything from the bottom and the walls of the tank and it settled at the bottom.

Any way I am gonna work on them tomorrow, I just did not want to take them all apart.

Thank you from Miami.
