Welcome to JUST ANSWER small engines, let me try to help you !! With the spark plug removed, does engine spin freely? With finger and rag held on spark plug hole do you have enough compression to move your finger? Do you have spark at the plug, when it is grounded to metal? If you have spark, put about a teaspoon of fuel in the spark plug hole, re-install the plug and see if it will fire for few seconds. If it does, the carburetor is not delivering fuel. Can you get the model number and type number off the engine? Example 123450-123-E1

hello,sovereign 375 family ybsxs 1581va 27460 spark plug out lot easier to pull toggle with finger on hole yes could move finger couldnt see spark when grounded maybe there was bit awkward to see so then i put teespone of fuel in srark plug hole it did fire for couple of seconds.so onwards and upwards hopefully

I think you have a carburetor that needs to be cleaned. If i'm right , it is the tank mounted unit. The site I have listed , shows your Briggs carburetor at the top. Shows how to remove and how to repair. With engine firing with small amount of fuel introduced into the cylinder, it has to be the carburetor not delivering the fuel to the cylinder.

hi curtis,well i cleaned the carb,one small problem the govenor spring i cant work out how it moves it i have got the main bar on but its the spring wires, i can move it with my fingers butit just like stays would it be alright to put it in the open position and leave it without the small spring wires on regards ian
Expert:  Curtis B. replied 4 years ago.
Did you look at the diagram on the web site linked? Which spring are you speaking, the small spring, wrapped around the link? It is just used to go from one end of the link to the other to stabilize the link. It is not important, and could be left off, the other spring is the important one. http://outdoorpowerinfo.com/repairs/briggs_10l900_carb.asp

hi curtis,checked diagram,there are 2 springs large and small,the othere bit is on,i just cant see when i move the lever at the side,how it works,if i connect one spring it closes it so how does it open its confused me.
Expert:  Curtis B. replied 4 years ago.
Lever only works when engine is running. Without engine running the throttle doesn't move, the governor controls it when engine is running.
