I never get rid of my old parts, they're inside plastic bins in my storage.
I was hesitant to return the original for a core but $75 is $75.
It was in battered condition, it's not like it was as scarce as a 4100.

If fuel is coming out of the bowl vent, you are definitely having issues with the float not setting the needle correctly. Is there any fuel getting in the plastic float? Take the float off and shake it. It looks kinda scummy, so if it's not getting fuel in it you might want to clean the float to make sure it's not sticking anywhere...

I thought my float was a solid piece of foam or something. But no, I haven't noticed fuel coming out when I pick it up. When it's in place it appears to float as it should. When I push down on it it displaces fuel like it seems like it should.

Show us a pic of the needle and float in place.

Did you clip the float and needle down to the port where the seat is?? Not clipping the needle and float down will allow the float to float up and pull the needle off the seat and will cause the exact issue you are having. Ask me how I know

I'll try and work on the photo tomorrow.

Yes, I always put the clip down, but maybe there's something I'll missed, I'll have to take a second look tomorrow.

And this is part of the reason why I want to sell the car, no time to fix it because I have to watch the kids. I just want to drive it.

How old is the gas in the gas tank? If it's been in there for 2 years while you worked it it needs to be drained.

From looking at those pics unless it's the light the fuel in the carb looks like varnish. If it were me I'd pull that carb off now to at least clean it thoroughly and replace the fuel filter before running the engine anymore the raw fuel is wiping all the oil of your cylinder walls like someone posted earlier.

Just my opinion.

To the next guys like me that are about to re-fire after several months or even years of downtime;
Better driving through chemicals.
Fill the carb through the air vents with a mixture of fuel and a treatment of your choice. Ahead of time is great. Remove ignition coil and crank a short time and refill with the supergrass a few times.
Rest.
Connect coil.
Lets hope you ve been treating your fuel and taking precautions for ethanol the last few years.

If that kind of residue is all in the bowl and on the float, it sure would be in the booster venturi passages. I would take it out and give it a good cleaning through all the tiny passages. With the carb OFF the car, of course. That booster venturi is the heart of the 2100 and it needs to be very clean to work properly.

I second the vote for the problem being old stale gasoline. Dave R.

How many people second the buy a new carb from Autozone option?

I consider my time too valuable right now. I'm struggling to type this as my 1 year old is trying to get to the keys on the keyboard...

Oh, and I'm going to drain the fuel tank, fuel lines, replace the fuel filter, etc, no issue there. I just need to figure out where to take the old fuel.
