Hi my name is ***** ***** thank you for using Just Answer. once it gets hot does it shut off ? , if so we need to check to see if your losing spark or compression , how long does it have to sit before restarting?
Customer: replied 2 years ago.
I let it sit for an hour and it ran fine.
Customer: replied 2 years ago.
When it is in that hot mode, it begins to run rough and then it stalls. If I use the choke I can get a few more minutes out of it.
Expert:  Briggs-Fan replied 2 years ago.
Once it dies have you ever tested IR for spark after it dies ?
Customer: replied 2 years ago.
I'm sure it has spark because I can start it immediately....it just runs rough and eventually stalls.
Expert:  Briggs-Fan replied 2 years ago.
Ok , just making sure it's not a coil issue , are the fins clean ? Etc
Customer: replied 2 years ago.
The top end of the fan is clear. However, I'm wondering how clogged up things are further down.
Can I take an air hose and just start blowing everything out?
Expert:  Briggs-Fan replied 2 years ago.
Yes you can , I'd remove the blower housing to makes sure no mice nest are blocking the flywheel from cooling the motor etc
Customer: replied 2 years ago.
The blower housing looks like it might be a complicated removal. I'll give it a try.
Expert:  Briggs-Fan replied 2 years ago.
Can you give me the make and model of the engine and I'll look at a diagram
Customer: replied 2 years ago.
After removing about nine screws, I was still unable to remove blower housing. I lifted up enough to see most of the fins which I blew out with 100 lbs of air. The fins look pretty good. Its a Simplicity Regent 14HP Hydro Tractor. Mfg No.(###) ###-####
Customer: replied 2 years ago.
Make that Mfg No(###) ###-#### ***** read this one off the tractor chassie. The first one I gave you is off the Owners Manual.
Customer: replied 2 years ago.
Its a Kohler Command High Output Series.
Expert:  Briggs-Fan replied 2 years ago.
It should have 4 to 6 bolts around the sides that loosen or come off to get the cover off , might have to undo and remove the air filter etc but the motor should have a model number on the shroud somewheres like sv590s etc
Customer: replied 2 years ago.
After removing the screws, I put it all back together. Some of the screws were a real pain (hard to get at). I don't plan on doing that again. You'll have to go with the info I already gave you.
Expert:  Briggs-Fan replied 2 years ago.
Ok I will opt out and let another expert take over because for all we know if there is grass or debris or a mouse nest under that blower housing that could easily cause a overheating issue . It's just to hard to diagnose if we can't check .
Expert:  Briggs-Fan replied 2 years ago.
I really want to help you resolve thus issue, can you locate the model number on the engine itself for me, I then can try to find a diagram or walk you through removing the blower housing . My cancer is if there is alot of grass in the fins etc than it makes me wonder if the flywheel fins or around the flywheel itself are blocked .
