Small engine question

[RangerClay]

Near the end of last winter I noticed that gasoline was dripping from the adjustment screw on the carburetor of my snow blower. I pushed up on the screw a couple times and it stopped dripping.

Fast forward to the week. I filled up the gas tank and got it running for this winter. It's dripping again. What is causing this?

I am not a mechanic Joe, but my first thought would be that the adjusting screw has an o ring and that o ring has probably deteriorated enough to let it leak.

i agree with the above. but you have another problem maybe. the gas left in your snowblower turned to varnish over the summer, and is no good. (unless you added stibil). you most likely need a carberator rebuild about now.

whenever you shut an engine off for the season, like a lawnmower, snowmobile, 4 wheeler, outboard motor from your boat, etc, you should pull our all the gas, run the engine until it stops running (out of gas totally) and put it away dry.

and that's about the extent of my mechanical ability and i paid dearly for it...:yes:

Steve has a very good point on letting the engine sit. Have quit using stabil here and now always drain the gas from the tank and run the engine until no gas is left, just did this with my tiller yesterday afternoon late. Carbs will get all gunked/gummed up if you leave gas in them and even with stabil you might still have problems. To get all the gas out, you may have to run it with the choke on at the very end of it running.

yup. do this here as well. i've never used gas treatment products like stabil.
