MF 35 utility

ok I need some advice . My trusty ole 35 has a problem , it appears to be spewing gasoline out the dipstick hole while running. it is cold snowy and I have limited daylight to view what going on but today i had a helper , I thought I was leaking antifreeze or the gas tank had a hole but we found it was gas coming out the dipstick hole and I mean a geyser . I see many posts about oil spraying out but this is gas . Is the motor shot ? I;m not sure where to begin/

it is a 1963 35 (yellow)4 cyl gas with a loader bucket

it has been used . its now a show tractor
 
I will visually verify this tonight but it looks like the Mech pump is attached to the sediment bowl which is up under the hood so I really never looked up further than the fuel shut off on the bowl.

Could this flood gas into the oil pan ? literally gas is gushing out the oil dipstick hole as if it was a bilge pump.
 
Could be a stuck open float on the carb. My 1520 shutoff solenoid didn't close and flooded the engine with fuel,mine hyd. locked when I tried to start it,lucky for me it didn't bend anything,drained the oil and drilled a hole in the bottom of the rubber connecting hose to the carb so if it happens again I will see a puddle of gas on the ground.Been about 5 yrs. with no problems.My gas shutoff is hard to access up under the front end otherwise I would shut it off.I guess that's why they put a electric one on it.I would pull the float bowl and see if there is something in it to stop the float from closing,that is about the only way gas could get in the sump.
 
If the float stick or you get dirt etc. in the needle valve it can/will fill the oil pan with gas and that is a major problem if you run it for more then a couple minutes. What happens if the gas builds up in the air cleaner tube and wicks/evaporates into the engine an into the oil pan. One should always shut the gas off when you park a tractor so that does not happen. Got a call from a guy a few years back because his 9N Ford over full in the oil pan. Went and worked on I and I drained 5 gallons of gas and oil out of the oil pan and it should have only had 5 quarts of oil
 
For sure is Gravity fed ...hope the Pic attached . So now I'll check for a sticky float in the carb.
Its a brand new carb with maybe 6 months of good use on it and it ran fine thru hot summer and freezing winter ...maybe got junk in some gas to botch it up ?.

Gravity fed systems have a fuel shut off for a reason. As others have said, use it even if you consider it a PIA.
 
All it takes is one little piece of rust to cause the float needle to not shut off the gas as it should which in turn means gas in the oil which in turn can lead to a blown engine. Take that little L shaped valve and turn it off when not using it problem solved
 
Thanks for all the advice , I used to shut the gas off after each use because I had a slight leak from the carb, I replaced the carb and fixed the leak......or so I thought, well now putting the pieces together it appears the leak is still there but its going in the crankcase rather than on the ground . I'm going to add a shut off valve to the gas line in a better place and get back in the habbit of shutting it off.

Thanks Again everyone.

I wouldn't bother adding another fuel valve if that one works, but I do suggest adding an inline filter under the battery tray area (away from exhaust heat)

And double-check that the screen is actually fitted to your fuel bowl.

I added an inline filter under the battery tray, it's a pain to get to, but doesn't need to be changed often. It's extra insurance.
