Lawnmower smells of gas for a couple days

it's got a Briggs 4.5hp - about 7/8 years old - rebuilt the carb 3-4 years ago - after use it smells of gas for 2-3 days. I don't remember this being a problem when I rebuilt a few years back - I think surging was the problem then. TIA

I had a power washer that had come to realize the joy of ethanol in the gas. The float got so gunked up from ethanol sludge that the float needle did not make a full seat in its gasket. Thus the gas in the tank slowly dribbled out. Had the same gas smell until I rebuilt the carb and cleaned it out.

When in doubt clean and/or rebuild the carburetor. You did not say what lawnmower or motor you have so it's impossible to get specific.

Now governor probelm

Update - did the rebuild kit - gasket, diaphragm and screen - also broke the idle governor spring and replaced it. Now it will not stay 'up to speed' - I'd say it probably at 1/4 the revs it should be, stalls under almost any load - if I take off the air cleaner and manually 'override' the governor it will get up to speed, but not stay on it's own. It's like the new spring has too much play - but I took the old one in and we looked up the model number and the new one looks just like the old one.

Post the engine numbers usually stamped in the metal engine shroud just above the spark plug and someone will tell you how to adjust it. Have a good one. Geo

And to be clear - the spring I replaced is the wimpy one closest to the engine

Here is how it should be hooked up, to increase the speed bend the tab where the spring is hooked in the slotted tab forward at the base of the tab, not up or down, forward. Have a good one. Geo
