2019 Craftsman T150 46" Hydrostatic 19hp Riding Mower

Mower in great shape! But, it started to smoke a bit while mowing. Stopped immediately and googled as to why? Gave me some things to check for and try to fix the issue. I did one of them and, it did seem to help. Then, I decided to replace the fuel filter while I had it open. Ordered the one it said, was for my mower. Installed it only to find out that, it was " Not" the correct filter and, as such, ended up flooding my mower badly. Took out the spark plug, let the cylinder dry out . Bought a new plug and installed it. But, now I can't get it to start or, even barely try to crank over. I had a similar issue about 8 months ago but, with some help, got it back running! And, it's been running good ever since, until about 3 days ago! Now, it's like the engine has seized or something once again. I tried what I could but, with no luck! So, I'm done! I am not a mechanic or small engine repair guy nor, do I have the patience , money or time to investigate and work on trying to figure this issue out. Other than not starting, the mower is in great shape! Even the paint! Has newer Battery, Blade belt, Deck belt, Spindle's (2), Blades, Engagement cable, Starter, Solenoid,Fuel filter, Oil filter, Oil, Air filter, Spark plug, etc.. Don't want to deal with it any longer.. First $500 takes! * Note: Bagging system not included at this time!
