lot of gas out. Ran good for about 5mins then it stalled and stated to blow blue smoke. It will stop can restart but it will start the same thing. It also blows oil out the fill tube if you take the cap off. Terry

Experienced gardeners share their insights in answering this question :
The oil out the fill tube is normal with the cap off, believe me I know about those un expected showers. Your problem sounds like fouled plugs because of the gas bath. Put in a new plug/plugs and I’m sure you’ll be all set.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
Clearances differ for the two valves and typically range from . 002 – . 004″ to . 005 – .
When measured on a cold engine using a feeler gauge, valve lash for the Briggs LO206 engine should be . 003-. 004 inches on both the intake and exhaust exhaust side.
The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something`s wrong with your battery, your car engine won`t turn over.
If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
Check – Slip the gauge blade between the rocker arm and valve tip. Move the gauge forward and back and feel the resistance. If you feel a nice amount of resistance, meaning, the gauge is snug but does move when you push on it – Your good, no need to adjust this valve. If you don`t feel any resistance, start adjusting.
Use Carburetor Cleaner
Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.
If there`s too little valve clearance, the valves won`t fully close, causing excessive heat, and the engine will lose power.
Valve Clearance Tips
Recommended valve-to-piston clearance is generally 0.080-inch minimum on the intake side and 0.100-inch minimum for the exhaust valve. The exhaust needs a little more clearance because it expands more with heat.
To perform the procedure rotate the engine by hand, as soon as you see the exhaust valve begin to open adjust the intake valve. Once adjusted continue to rotate the engine until the intake valve opens entirely and just begins to close, now adjust your exhaust valve. That cylinder is now complete.
Use a ring spanner to loosen the locknut and turn the screw clockwise to decrease the gap, and the opposite way to increase it. When the clearance is correct, hold the screw with a screwdriver while you tighten the locknut, then re-check the clearance. There may be a self-locking adjusting screw with no locknut.

My tractor stalls like it is starved for gas although the gas tank is full. I,ve changed the fuel filter and the gas cap. I’ve cleaned out the gas tank, gas lines, and the carburetor bowl. The problem seems more acute when the gas tank is full or near full. At this time to alleviate the problem, I blow through the gas cap and the fuel filter fills with gas and it runs good again. But as soon as the fuel filter has no more gas, of course, it stalls until I blow on the gas cap. As the tank gets down to about 1/3 full, the engine runs OK. What else could cause this condition?
ANSWER : I had a similar problem with a sears tractor. close to the carbarator is a rectangle box with a rubber hose going to the engine block – remove the hose and spray carb cleaner in the hose wait a few mins and try again – its a vacuum for the carb
