I have a 446 and I just put in a new brass float. Ever since I put it in, gas pours out the top of the carb. I set it to 1/8" and no help. I tried everything!! My old fiber float didn't do this. What could it be? The needle is clean, it has a electric pump. Any help would be great!! thanks

No, i did not get a new needle or seat. It still looked good so i figured i could still use it. I dont think that it is rubbing but it is so hard to tell. I am not sure what the output pressure is for the pump. It was on there when I got it and I never messed with it. I figured since the old float worked fine with it that the new brass one would as well. The new float did not come with a new assist spring. Thanks!

I changed it to 1/4" but still nothing. Its not shooting out the like a fountain but it is more like coming out that top hole a little. It's slowing coming out. Not alot but some. If I put my finger over the hole it runs fine but when I let go and extra gas goes down the carb it runs terrible. I don't know what to do at this point. I tried everything that I can think of doing.

Boomer-I used the one that was one there from before. It doesn't look beat up too bad. How would I be able to test to see if that is what is happening? That would make sense because it is not shooting the gas out that hole. It is more like slowly dripping out. I will check it again to see if I see any damage. Thanks guys!

ricohman-I was thinking thats what is happening. I am going to try and see if I can even find my factory pump and maybe stick it back on. If not I will probably get a new pump and see if it helps. I am going to hook up a gravity feed tank tomorrow and that will tell me if it is the pump or not.

Thanks everyone. There is no gas in the float. Also about the fuel pump. It is a DD carb. What i meant was i need to find the other parts to the fuel pump because the only thing that is part of the fuel that is on the carb is the end piece where the fuel line connects too. I will get some pictures of the carb and float later today. I am leaning towards that the pump is too powerful. The pump was on there when i got it so who knows it could be putting out way to much pressure. Also, the float gap is about 1/8"-3/16" and the float only moves up and down like 1/16 of an inch. Is that normal? It moves freely and I can see the needle opening and closing. Could I lower the pressure on the pump by adding another filter or wouldn't that help? The pump is back where the fuel tank is, so there is about 3-4 feet of hosing plus a filter before it gets to the carb. I will tinker with it some more tonight and hope I get it running perfect! Thanks!

I finally got some pictures for you guys. Here is the carb, notice the orginal pump is off. I found the orginal pump but it does not look good. I think that the top gasket on the carb is bad. It looks like it is leaking out of the side of the carb as well as the top. Can I buy just the top gasket instead of a complete rebuild kit? I am ready to through this carb out in the yard and rig on a new more modern carb!! Is that possible?!

Here is another picture of the carb.

Here is the picture of the pump. No markings or anthing on it. mmhhh

Well I am on a role now so I will keep going, a picture of my homemade weight box.

And my homemade plow.
