Engine burns oil and dies

[AdamHword]

It’s a 18hp vanguard engine from the 90s but it’s burning oil and gasoline is getting into the oil. It’s also runs, sputters and dies

IT needs a carb rebuild / replacement.
Fuel is overflowing through the carb into the engine then into the sump thinning the oil

Yup, carb needle and seat issue as Bert said.

Make sure you change the oil a couple times AFTER you get the carb fixed 100%.

Is the spark plug fouled? Is the compression low? Bad rings could be a contributor. In which case rebuilding the carb is putting new wine in old wineskins.

All new carburetor

All new carburetor

WHERE did you get it from? Amazon or Ebay? Guessing Amazon as you still have a carb problem.

Either rebuild your old Briggs carb or replace with a new OEM Briggs carb.

Well their is only 4 ways fuel can get from the tank into the sump, in order of the ocurance .
1) overflowing carb
2) fairies
3 ) leaking pump diaphragm
4) young child "helping daddy"

5) Severe blowby (broken ring/s). I've seen this ONCE (on a badly rebuilt car engine).

Replace the carburetor fuel solinoid on the bottom of the float bowl or fit a fuel shut off valve in the fuel line, turn off the gas when it's not running. Also make sure the needle and seat is working properly.

Also make sure the needle and seat is working properly

Great tip.
