Toro rear bagger model 20672

Hi guys;
This may sound familiar but I have a Toro model 20672, serial #3005***. Cheese had helped me through getting it re-running back in August. It has run perfectly after that and I used it several times with no problems. Yesterday I go to prepare it for a winter lay-up and decided to use it one more time. Now it is a she-dog to pull the rope starter and there is oil coming out the muffler. No matter how many times I pull it won't start. Pulling that rope is a REAL pain as I had my rotator cups resewn (again) and am leary of re-ripping them pulling on that chord.
Any ideas what may be causing this? I am thinking that maybe the rings have gone and that this one may be destined for the junk yard.

Check the compression.
Have you had it tipped over to change the oil?

Hey joe....

(wasn't that a song in the WW2 era?) Thanks for the comeback. I haven't tipped it over as I change the oil through a front plug. When I pull the spark plug out the rope pulls easily. Just when the plug is in place it is tough. As I had said it ran good then when I put it away and tried to use it again ... blah...........
I have noticed some oil on the floor where it was stored. Since that dip stick is almost impossible to read with new oil maybe I'll re-drain it to make sure that the level is right and it is not the problem. So easy to misread a shiney white metal dip stick coated with clear oil.

A very common thing to happen on an engine having sat then having an overfill of oil is the gasoline leaking from the carburetor into the cylinder and down into the oil. The overfill in the crankcase plus the gas leaking into the cylinder hydro locks the engine, making it difficult to turn over.

Removing the spark plug and changing the oil is a temp fix. The problem is usually in the carburetor, though, with the leaking. That has to be taken care of.

I think that.......

...this mower has given its' last gasp and has gone to the meadows in the sky. Yesterday I pulled, cleaned and reinstalled the plug and carefully changed the oil. After a good amount of pulling it finally started and gave a nice long run of about 10 minutes. Then it happened, it coughed, starting throwing brown liquid out the air filter, gave a big bang and really starting throwing liquid, from places that I couldn't believe. It then started to give heavy white smoke and stopped. The liquid I was the oil with a gas smell.
I don't think that this old workhorse is worth the parts, and time, that will be needed for salvaging.
Anyone concurr on that?

Well, a few bucks for the carb kit and whatever your time is worth.
