    Think my governor spring is stretched and isn't working properly. I have full throttle, and that 's it. tends to cut out when mowing as well.

I have no solution, I have the same problem, engine runs full speed WITH THROTTLE PLATE CLOSED. I took the carb off and cleaned it, when I put it back on it ran full throttle with butterfly closed. I figured I had lost something so I ordered a completely new briggs carb and sure enough it runs wide open WITH THE BUTTERFLY COMPLETELY CLOSED. I know that it seems impossible, but is true. I need help.

    The post I did above about full speed with closed throttle plate is on a briggs&stratton 14.5 HP engine.

Why don't I get spark on my briggs and stratton 3.75 model 98902


Did you check the ignition shutoff wire? Make sure it isn't grounding. It is a common Briggs problem. Take the wire off of the switch contact and check for spark again.

I have a Victor 4-stroke (sprint 375) which is 8 yrs old. Never missed a beat until yesterday where the engine now revs, then almost cuts out, then revs, then almost cuts out etc. All 'obvious' components...


You need to take the carb off and clean it out real good.i would suggest taking a bread wire and run through the passages in carb then soak in mineral spirits or other cleaning solution.blow out with air hose.

The engine on my Sprint 375 floods when trying to start


Check the float in the carb. bowl for gumming and clean your carb.. If you haven't done so already. Or you can try running a fuel treatment through your fuel. That may help you with your flooding issues. Good luck.

Mower stutters when i turn up to full throttle.


Hi if it is older than 2 years it will need a new diaphram and gasket under carby you will also need to clean out the fuel bowl in the top of the tank this should fix your problem.

Poor running engine on my lawn mower


I think you need more than a screw adjustment in the carburetor. It sounds as if you need a full tuneup. This means air filter, gas filter , carb. rebuild ,spark plug etc. Good luck. donnyb60
