Put a new fuel bowl on my 8N and now if I don't shut the fuel off after I shut the tractor off, gas runs out of the carb...Normal? Or can I adjust the fuel bowl to stop this?

Also, solenoid makes a buzzing sound, almost like electrical short when I hit the starter. Have a new one on order, could it be the starter? I tried tapping on the solenoid, but that didn't help.

Carb leak is either a float problem or a seat problem. Floats do go bad or stick and the needle seat can get dirt/rst in it and cause that problem. Some times taking the drain out of the bottom of the carb and letting gas flow for a few minutes cleans out junk in the seat and will fix the problem. Now on the soliniod that could be as simple as poor connections some place or a stuck starter gear on the flywheel or a bad starter.

I think gas running out of the carburetor is because the float is stuck,or got a hole in it,holding the needle valve open,causing gas to run out of the carburetor.

Like Ross sez, turn the fuel off at the sediment bowl when you put the tractor up for the day. (See tip # 9, below) This is one of my favotite posts on the subject:

"We just had an 8N in the shop that the owner wanted us to fix the carb leak and replace the starter because the engine wouldn"t turn over. Turns out the base had more gas in it than oil and the bearings didn"t get enough lube from the diluted oil and seized the engine. I think of that tractor every time I park my tractors now and don"t forget to shut the fuel off."

If gas leaks out of the carb w/ the fuel on & the tractor off, the fix is in the carb, not the sediment bowl. You have a bad/sticky needle valve or seat or a float problem.

Chances are the solinoid is fine, but your cables or grounds are bad. Here is another great quote:

From a post on 12/31/07:

“My starter motor quit turning the engine over. There was no click or anything on my 1947 2N.

I could hand crank the engine fine.

I got some new battery cables and cable to the starter which fixed it.

It really cranks up well now. I've got the original 6v system, and with the new cables it cranks up like it did when I had to jump it from a 12v back when I picked up the tractor from my grandfather earlier this summer.

It starts up immediately. Previously it had the original 1947 cables, which upon inspection had the inner strand wires corroded/severed.

Some of you guys thinking of doing a 12V conversion, if you don't need the 12V for some other electronics, might just need replacement battery cables.”

Try tapping the side of the starter with a hammer, while you hold down the starter button, it may just be that the starter isn't getting a ground.

You should always turn your fuel off at the fuel bowl cut-off and let the engine run until it stops due to fuel starvation. If you do not cut it off, it can empty your gas tank into your oil pan and when you start the engine, you will ruin it and require a rebuild. Probably $1,500.00 or more to fix it. A lot easier to cut off the fuel.
