Needing some help for a guy that I sold a lawnmower to. Recently had a carb issue. Too much gas got into the crank and muffler and it was gushing out. With that being said I attempted to get the carb fixed. No help from any local shop "You'll just have to replace it" Carb kit on backorder and I needed to get it up and running. So I just ordered a new OEM Kohler carb. This gave me the time to put in an in-line fuel cut-off swtich. So back to the engine. Once I put the new carb on it fired up and ran great. Just as it did before like new. So I decided to sell it and get another lawn mower since I had inherited my grandmothers newer lawn tractor. 2 days ago he came and picked it up. Fired right up no issues. He drove it onto his trailer and away he went. Probably got home and took it off and parked it. Today he txts and asks. "Hey when mower had prob did it spit and sputter than blow white smoke and die?" So I'm asking myself what could be wrong. Other things I did to the lawnmower this year before I started mowing:

Replaced spark plug with (E3 compatible spark plug from Lowe's)
Replaced fuel filter (Universal from Lowe's)
Replaced oil (4-cycle ProSelect oil 10W-30 Lowe's)
Replaced oil filter (OEM Kohler Lowe's)
Replaced air filter (OEM Kohler filter w/precleaner Lowe's)

So...... With that being said what could be the issue? If by what I'm telling you and I've never had a single issue with this engine. Any help or tips would be greatly appreciated. It's also note worthy to tell you that the 2-year warranty on the engine expires in June. I would hope if it's a major issue I can get it fixed. I keep my receipts each year when I perform maintenance for this very reason. I've never had an engine issue on any other equipment like this so don't know which way to go. Thanks guys!

P.S. You're the real experts here! I can't get much out of the local guys but guesses. :dunno:

Latest update... He replaced the oil thinking I hadn't from the previous flood before I ended up replacing the carb. When in fact I did. I may have put too much in. I want to say I remember the oil reading on the "F" (above the line under the "F" not below). He says it's running great now. We both agree it's just best practice to keep the fuel cut-off switch off when not using it that way there's no chance for gas to drain into the cylinder. Makes sense! :) What would you have done?

We have had similar issues. Sounds like it might have gotten some more gas in the oil, causing level to go high enough to overfill. Guy changed it and "fixed" it. Wonder if the float in carb got stuck open and let gas in? Having shut-off used will prevent it, not fixed though. We have taken machines back and swapped or returned money, in your case maybe this is best fix for now. Telling fellow to use some Sea-Foam in fuel might fix it if slight dirt in fuel?

Thanks for that Eric! Will do! I will tell you in case you lost me on the story. The carb was replaced days ago when he picked it up from me. That was originally a problem. With a new carb I'm sure the float didn't give any problems. That's most likely what caused the problem in the first place. :2th:

You be surprised even with new carb what could happen. The fuel system may have let grit in or a machining cutting in carb. Doesn't take much to hang float up!
