Hey guys, I recently got my H running after sitting for 20 years. when I first started it, it ran beautiful for about 15 mins, the engine started hunting and smoking black (fuel) and finally died with gas running out of the carb. I put a new float in in the carb and a kit (seals needle and seat) I put the carb back on started it, the hunting dissappeared but it ran choppy with still lots of black smoke. So, removed the carb again, re adjusted the float gap again. and set all screws to manufactures specs and started again. the H ran beautiful, I thought I had it licked but after around 10 mins off running she started running choppy again, and of course started with the black smoke and flooding itself out again. by the time I shut the tractor off gas was again pouring out the carb. I"m really starting to loose patience here, there must be something small Im missing. these are a pretty simple carb. When I put the carb on (for the third time) I turned the gas on and waited for it to fill the carb to ensure nothing ran out, as soon as I started it and drove it a bit, it started leaking. Any ideas guys?? I greatly appreciate any help!..... is it possible that the new new needle as seat could be bad??

Greg I dont know if anyone has mentioned this or not but on both my H's I had problems with the pin the float operates on,It would slip out after running awhile and gas would be every where and tractor flooded out. I fixed it by putting in a longer pin made from a nail and havent had any problems in this area in a couple of years. ED

I doubt that the needle and seat is bad or it would leak before you start it. As others have said check for crud in the tank. You might also want to take that float out and shake it to see if there is any gas in it. What you are describing could be caused by a small crack on the top of the float that when the fuel splashes around in the carburetor will get into the float and cause it to sink.

Check for crud and the float. Likely you will find the problem.

I"m going with the rest of the guys...it in the sediment bowl and/or tank. Mine did the same thing. New sediment bowl and it prrrs like a kitten. I also got the one that sticks up in the tank about a half inch so it"s not pulling the gas right off the bottom of the tank, where the crud builds up.

Look down into the tank with a GOOD flashlight, if there's that much crap in there, you should be able to see it. If there is, spend a few hours, take the tank off & clean it, be done with it. Then keep your gas cans clean too. I had a JD with some water in the gas, the only final cure was taking the tank off cleaning & drying it out. Never stalled since!

I agree with the other 2 probably junk in the tank getting to the needle and cause it to stay open. You might try an in line fuel filter, but not the ones made for cars but one that is made for a lwan mower. That will not really fix the problem but it may help. Depending on how bad the tank is it could fix it but if the tank is realy rusty it will only fix it till you clog the filter

Why not the ones made for cars?

I've had good luck with any I've bought.

We never clean out gas tanks, just keep filtering the stuff out and rarely have to change the inline filter.

If the bottom of the tank plugs up, I pull the inline filter out and blow into it to fluff the bottom of the tank. It works well and you remember why you don't like to siphon gas.

Andy, the reason that you never have to change the in-line filter is because the sediment bowl is already catching all of the impurities. If you have ever had the sediment bowl apart, you will know that there is a very fine mesh brass screen that the fuel has to pass through on its way to the carb. Anything that gets past that screen will also pass right through your in-line filter.

Actually that screen is not made of brass, it is actually made of the same exact material that is used in an in-line filter.

The ones for car don't work well on some tractors. The filters made for cars are also made to take the preassure of a fuel pump and a lot of times that is why they don't work well. A lot depends on the tractor and how the tank sits on them.

Greg,

The problem isn't the carb, it is the stuff that is running into it.

You clean the inlet, then dump in some more trash to plug it up again.

Clean the sediment bowl and tank if necessary. Any little piece of grit will hold that needle open.

Most likely you getting some varnish and possibly very fine rust from the gas tank. Before you take the carb apart again remove the gas tank and do a thorough chemical cleaning. The gum and varnish from the fuel that sat in the tank is very difficult to remove without some type of chemical such as muriatic acid. Another option is to take the tank to a radiator repair shop, and have them clean it.
