Marvel Carb problem

I have rebuilt my old TO 35 (1955) and I am about ready to take her out to the field and give her a work out. I pulled the tube from the oil-bath air cleaner to the carb yesterday and it had a lot of gas leak out. What caused this gas to collect in the air tube from the air cleaner? I have tried to adjust this carb a number of times and it still does this. Any help would be appreciated.

Cheapest solution by far is to turn off the gas when you stop it. The flow should stop when you stop using fuel but it doesn"t take much from an old fuel tank to hold the valve open slightly and allow it to leak.

I usually have the same problem after filling a carb that has been empty for awhile or after I've had it apart. If it fails to shut off I simply grab my pliers and rap on the bowl a couple times. It's just enough to get the valve to mate with the seat. It usually only happens to me after I've done a real nice job of cleaning and repainting of the engine so when the gas runs out of the carb it takes some of my nice new paint with it. Dang!!!! That makes me mad.

As George says shut off the gas when not in use. I may be wrong but assume the smell was when after the tractor had sat for awhile. If after it had been running, you may have another problem. Most on here have found it best to always shut off the gas, when not in use rather than try to adjust the float.

I've had two Fergusons, a TO20 for about 30 years and a recently purchased TO35. Both tractors had the same problem of float valve leakage when not running. No amount of work on the carbs helped. There is a company that sells an electric solenoid valve which can be spliced into the 1/4" gas line. I am thinking of buying one because it is such a pain to shut off the gas every time I shut off the engine. The problem---- the valve cost $60. I'm trying to come up with my own version possibly from a junk car. I think there are solenoids that feed the injectors on some cars. If you want the link to the company that sells the solenoid look back at another discussion where I posted the idea of an electric solenoid for the gas line. It was justa few days ago.

Your carb is overfilling with gas because the needle valve/float combo does not do a good job resisting the weight of gas from your gravity flow gas tank. You need to make sure your fuel shutoff valve is working (close the shut off, pull the drain plug on the carb, let the gas drain out, then leave it drip for a while to make sure the shutoff valve is preventing gas flow to the carb.)
Close your shutoff when you shutdown the tractor, that will fix your problem.

Thanks for the note. I will give that a look when I get back in the garage. I was about to take the carb off for another float adjustment. You may have saved me that hassle.
