Classic problem. Need to take the carb apart and clean it out. probably trash stuck in a supply passage, or, because of the ethanol, there might be gunk built up in the float bowl causing the float to stay in the closed position.

My dewalt dpd3300 ,why is it getting gas in the oil

This happens when the gas needle valve in the carburator sticks open. With it open, gas continues to flow into the carburator then into the cylinder and finally down into the crankcase. It can be caused by dirt in the needle valve's seat, a stuck needle or float. Most of the time you can remove the float bowl and flush out any dirt. If there's a lot you should consider flushing the gas tank and check your gas can for dirt. If the washer has been sitting for a long time the problem could be varnish is gumming up the carb works. Carb cleaner works well to flush that out. If the float, needle or seat is damaged you'll have to rebuild or replace the carb.

Gas shooting out of rubber hose above carburator. craftsman lt200 with kohler engine.

If hose coming off carburator does not connect to anything then it is the over flow for carburator when float gets stuck and does not close needle valve causing excess fuel in carburator bowl and is drained automatically through vent orfice connected to hose that gas is dripping from. If this is the case then remove carburator bowl, check float, needle valve and o-ring in where needle valve goes. sometimes when carburators sit over winter with gas in them the gas breaks down and over time will gel/harden and cause float to hang up and o-ring for needle valve to deteriate and not sealing properly. clean and replace parts as nessesary.
I hope this helped.

Gas continues to run from my 1987 Yamaha XLV snowmobile after the engine is shut down

The needle and seat in the carburator need to be replaced . Gas continously flowing is a stuck float which operates the needle valve in the carb.

You have a problem with your carburator.The problem is most likely the float, the needle valve ,or the needle valve seat. This isn't a difficult fix, you need to remove the fuel bowl under the carburator which is held in place buy a 1/2 inch bolt. There you will see your float, gently push up the float, it should be parallel with the upper section of the carburator. If not adjust float to make this happen. If float is off this is your problem, also float should not be full of gas, if so replace. If not we move on to the needle valve, remove pin that holds up your float and inspect your needle valve tip , if damaged replace. This could be your second problem,if not we move on to the third problem.The needle valve sits in a seat, it is about 1/4 inch round with a 1/32 inch hole in the center, top is flat, bottom is grooved. This seat can be removed with a pick tool. This problem can be fixed with carburator on the engine, but most of the time carburators are removed. You can do what ever you wish.
I believe the problem is with your float adjustment , you can fix this quick and get mowing again.
I am interested in how you make out. GOOD LUCK.

Tried to start and would then checked oil seems gas is going into oil what could be wrong

This is caused by a problem in the carburator, usually the needle valve is stuck open letting gas continue to flow into the motor even when the float bowl is full. Things to check for are that the float is still in tack and floats on the gas so it can close the valve. More likely there is something stuck in the needle valve holding it open. If the needle valve tip or seat is damaged it can also cause this problem.

Gas flows from cutoff valve to carburator hose connection but does not flow into carburator. What is blocking the flow?

On the top of the carburator there is a needle valve, closed by the float lever. 
If the carburator chamber is full with gas, the valve is closed and no more gas can enter the chamber.

If the chamber is empty and no gas flows inside, the valve may be stuck in closed position. Cleaning or some sharp (but not very hard) knoks on chamber cover may help.

Some times the float gets broken and falls down. This is a bigger damage, because it may lead to carburator overflow.

What do you recommend to solve gas in oil problem with Atlantic 500?

If you are getting fuel in the oil it can only be coming from one place. The float needle valve in the carburator is sticking open causing fuel to flow from the carburator into the combustion chamber, past the rings and into the oil. The only fix is to remove the carburator, remove the float bowl and the float. Remove the needle valve and clean the needle seat. Inspect the needle valve tip to see of it is damaged in any way. Remember while you are inspecting the needle seat that the smallest of particles can cause your problem.

Tiller won't start.

I recently had the same issue with a tiller that hadn't been started in over 8 years. Turns out that old gas had left a varnish coating in the carburator keeping the gas from feeding. Rebuilt the carburator with new float, needle valves and bowl, new Welsh plug. Fresh gas and two pulls later it went to churning. Took a short time to adjust the two needle valves for idle and full throttle and we went a-tilling.
