Sounds like you have some rings broke. Does it smoke when running. Broke rings especially the oil ring lets oil get out of the crank case and run out the exhaust and carburetor. This oil is burning with the gas and burns very poorly, also you have probably lost most of the compression which will make it run poorly. If you are mechanically inclined you can replace the rings fairly cheep. Of course you will have to tear it all the way down to get the piston out. Don't run it again because you are running the risk of scoring both the piston and the block. This of course will ruin the engine. You have a major problem but you can almost buy a new motor for what most repair shops will charge you to fix it. I would looking around at some of the small engine repair shops for a used engine. Sorry no good news but it is not an uncommon problem. I have two 10 HP that I am going to have to put rings in myself.
Good luck!

wipe off all o-rings well and apply vasoline to them all to ease install. I push down on rails in a circular motion to get o-rings to slide into place.
Should have o-rings remove those and lowe's,hardware,home improvement,plumbing supply stores should have what you need.Be sure to use plumbers grease or Vaseline on new o-ring and inside spout to keep from tearing new o-rings.
Low compression, and lots of blow-by forcing oil into the air filter via the the crankcase breather. Sounds like you need a top end rebuild. If you can get your hands on a compression tester, then check it. If it comes in under 120, then certainly time for a tear down and top end rebuild.
If you put a quick squirt of oil down the spark plug hole and if the compression pressure goes up on a second compression test, then rings/piston/bore are worn. If it does not come back up, then it may be leaky valves, or a blown head gasket.
do the compression test first. That will tell you where to start. Or, if you have the tools, tear the top end down and inspect. A motor re conditioner/machine shop will help to measure up and tell you if piston, and bore are ok. May just need new rings to freshen up.
Happy to answer any questions that you may have.

Most likely you have low compression caused by stuck piston ring or a scored piston and cylinder. This unit was made by Poulan and they have had an epidemic of this problem. The solution is to tear the unit down and put in new piston rings. Before you install the new rings you need to get a sheet of glass and some 600 grit wet dry sand paper. Sand each ring down about .002 to .003 and reinstall. This should solve your problem as long as you have good fire and the piston and cylinder is not scored.
Your cylinder could also just be worn out. This blower has a fairly short engine life.

I did this job on my 3.1 about 2 months ago and i forgot to put the ("O") ring on back fuel rail. had a fuel mess!! had to tear down plenum to fix, in my case i lost the o ring on rail and forgot to put 1 on. I had to order 1 from chevy garage, and replaced it. cost 9.00 just for 1 little o ring. mine fit tight also!! see if o ring is ok, and check line. car runs fine!!
If you have the tub out the seal can be removed by taking the brass ring off the shaft, its on top of the seal, then grab the seal with a pliers or pry it out with a screwdriver etc. The new seal will cost about $40-$50. when you put the new seal in put the rubber part on first, careful to not tear it on the slot cut in the shaft to mount the basket. Next put the old brass ring on top of the new one, use this to push the new ring on, this will help get it over the notch for mounting the basket. When the new ring is ontop of the seal remove the old ring, reassemble, check for leaks.
