May be time for a tuneup. Change spark plug, oil, air filter, sharpen blade and might even have to have the carburetor rebuild or a safety feature may not be working properly. Like the cable on the bail is not taking off the brake off the flywheel.

Pull start on a 5700 watt generator is locked up. Tech left the fuel shut off ON over night. It filled my oil up with gas. I drained all the old gas and oil out. Refilled it with 37 ounces of 5w30

Did you remove the spark plugs and drain the fuel from the cylinders? The gas in the oil was definitely a sign that the oil needed draining and replacement, but the pull start may be hydro-locked in the cylinders are full of fuel.

Ran perfect last yr , gas was stale drained carb bowl and replaced gas it started up right away then cuople mins later it started blowing oil out of the oil over flow tube

Sounds like the Needle valve in the carburetor is stuck 'down' letting gas continually run from gas tank into carb. When the valve can't go up (Close) gas will run past the carburetor and into the crank case I bet your oil is full of gas. Check oil level see if it is overfull

Ktm exc 250 2001 model starts then bogs out exspansion chamber full of oil and when i say full it was running out of it

More than likely it's not oil running out of the exhaust. It's excess gas cleaning out the carbon in the exhaust which looks like fresh oil running out. I would check your float in the carb. It's probably running over and filling the cylinder with more gas than it needs.

Unit not starting

Check age of gas. Cannot be more than 30 days old.
Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Always use the proper oil/gas mix. If you do not, your engine will suffer rapid, permanent damage.May need to clean or replace carburetor.

1995 blazer cylinder full of fuel. starter wont engage changed fuel pressure regulator.. ran great then wouldnt start

Check oil at dipstick for too much gas in oil thinning it to the point where the engine seized and won't turn over. If the cylinder was full of gas, this is a possibility. If the cylinder was full of gas, the fuel injector(s) might be stuck open causing this problem. Good luck on this problem.

Starts with starting fluid runs for a few seconds then shuts down

Good test. Do not keep doing that.
Make a new and accurate gas/oil mixture. Empty and refill. Secure cap. Be sure to flood system during start attempt. Can you smell gas? Oops, too much, better wait 30 seconds for full evaporation.
Two little screws near carb. Both are actually needles and probably have a visible spring which keeps them from vibrating to a new position while in use. One fuel/air mixture at low idle (start). One fuel/air mixture at high RPM.
Try 1 1/2 full turns open from fully closed. Once to get it to idle roughly, adjust to a smooth idle. Do the same at full throttle. You will notice that the more you shut the full throttle down, the higher the RPM will go (assuming that it is near correct). Do not run it to lean. The mechanics of the motor needs the oil from the gas.
Smile always.
