I've got a Kohler Pro V-twin 27 hp engine in my Craftsman DGT-6000 riding mower.
It's been sitting for a while, and I finally got around to trying to get it started.
I can spray starting fluid in the carb and it starts right up but only runs for a few seconds and dies.
If I try to start it normally, the engine just cranks but doesn't fire up.
I've soaked the carburetor in carb cleaner fluid for 15 minutes (I didn't disassemble it though, so I'm not sure the fluid was able to get into every crevice).
I've replaced hoses, fuel pump, and fuel filter. Fuel does flow through all the lines when the engine is cranked.
Thanks, guys. I'll do a more thorough job with the carb and check into the solenoid if that doesn't do it.

Cleaning a carburetor with the dip cleaner require a complete break of the carburetor removing all rubber parts. This why many of us techs have switched over to ultrasonics for cleaning with soap and water.
As for using the dip cleaner it will take several hours to do it job. Fifteen minutes is no where enough time. When I used it to soak carbs, it was usually overnight. Now that I use ultrasonic cleaner it is 30-90 minutes on most carburetors and you don't need to fully break the carburetor though some disassembly is required. Of course extra dirty carburetors takes longer.
Also those fuel solenoid are cleanable in ultrasonics. Most will cleanup nicely but there is also those that don't, still worth trying considering the cost of these solenoids.
I’ve never used a dip cleaner or ultrasound cleaner for nearly the length of time StarTech does and 99% of the time have no problems. When using an ultrasound cleaner my time is 8 minutes, with the temp at 45 degrees C, using SimpleGreen as my agent. If I use a dip cleaner, the max time I use is 3 hours. Different strokes for different folks.
I do not own an ultra sonic cleaner. Watched several videos on them, big ones for car engine cylinder heads. From small to big dirty part, seemed like they still required more cleaning. Maybe you guys have good luck with them. I was never impressed enough to get one.
Now if was are talking about a real parts washer, as in the wife's dish washer, I'm sold. Put that sucker on pot scrub cycle and look out. You need sunglasses when the carb body comes out. There's no need to redunk for more minutes here LOL.
I have worn out one and am working on fitting a transponder to an old washing tub
The first one did not have a heater so it was a 30 minute wash.
That cleans up old caarb like new
Dipping in solvent cleaners was always done overnight cold.
last thing before locking up first thing to be done in the morning.
Get a jewelry cleaner from harbor freight they work good and cost less I have had one now for about 5 or 6 years with a heater with no issues

My first ultrasonic cleaner was a small low power one. Not that impressed. Now i have a commercial grade one with sweep and degas functions. Night and day difference. I used to dip carbs. The OLD Gunk or Berryman cans of parts dip were awesome. Removed everything including paint. The new $hit is worthless.

Before I got my US, I used the Barryman's. But I'd place it on top of the A/C compressor, in the sun. Every time the house AC would kick on, it would agitate. By the end of the day, it was done. Except I never had much luck with the dip. It never did a fabulous job. Just sort of little above average.

You must have been using the new stuff. The good stuff i used was 30 years or so ago.
