So I am working on a buddies old 1970 c30. Had been sitting in his grandpa's field for 10 or 15 years. We pulled it to my place and I started going through it. Cleaned out the fuel tank, cleaned fuel lines new oil spark plus greased everything up.

So I rolled it over and it's running. Ended having to suck fuel through to make it keep running.. dry lines. So Im all happy until I go to shut the hood.

The engine is a 292. The carb is dumping fuel out a port that I don't know was used for anything.

I believe you should be more concerned with Gabriel's engine at this time.

Sediment in carb stuck float not allowing float to push needle to close off fuel. I would pull the carb off and clean

Might as well get a carb kit and rebuild it right now, once that old thing see ethanol it will be leaking out every seal and gasket within a very short period anyhow guaranteed.

Yup, a carb kit, float and new filter should take care of the problem. Did you put a new set of points, a condenser and check or replace the cap and rotor along with the new plugs?

The 292 is great engine and it will be running and working for years if he takes care of it.

I have been running ethanol blend gasoline in my fleet of old gassers for the last 15 years at least. Circa 1973 to 1984,consisting of 292,250,300,350,360,366,427 engines. Also numerous small engine pump,auger,mower,snow blower engines. Have not experienced any of the seal and gasket leaking you speak of.

Since its only been 15 years chances are thy have already been rebuilt at some point since ethanol has been main stream for around 30 years now since the mid 80's at minimum.
Not saying all will leak but a vast majority will develop issues.
With the increasing amount of ethanol levels in gas will only accelerate the issue too especially if it is on an engine that doesn't get the gas replenished at least once a month.

None have been rebuilt,all were purchased new,one owner. Ethanol was not mainstream in the mid 80's. We could get it for farm use in bulk, but it did not hit the pumps til much later. These vehicles sit in the shed all winter,fire them up in the spring and go.

Could be, I know on the farm in the 80's that all we ran too in bulk so that's why I was thinking of it this way, I was a big user actually nothing but up until a few years ago and had been having issues with random small engines for several years and suspected the ethanol but what put me over the edge knowing for sure was buying a brand new generator and filled it with ethanol and about a month later had gas running out of the carb, took it back where I bought it and was laughed out the door and explained in great detail that there is no small engine mfg that warranties any fuel related component due to ethanol use anymore, also had to buya new carb for a new generator that had never seen use yet, talked to several other small engine shops and they all had exact same story about fuel and warranty ect. After that I had even more issues with pretty much all of my small engines and I then made the switch to 91 ethanol premium and now wish I had done it sooner, been 3-4 years now and never have to mess with carb adjustments anymore and the things start and run way better too most that I had to mess with for an hour every year now start with 1-2 pulls the first time use every year.
