I had one that did the same thing.....it was noted to spin fuel/oil mix onto the concrete floor under it, while just trying to start it. A new seal stopped the leak and made it start better, too. There is a special seal puller for them but I was lucky...I had a self-propelled model; so I just took the gear box off and got the seal out that way. I did have to make a new gasket for the gear box. (This was an "F" engine. Not sure if yours is the same.)

If you split the engine you have to use a sealer on the two parts when you reinstall them on a F engine.

Right. I was just saying that because mine had the self propelled gear box, in THAT case, I didn't need either the sealer or the tool. I didn't need to split the case, in this case, if you pardon the dumb pun. (-:
