Yup, I Coked a carburetor and I liked it. Here is the story.
The other day my nephew dropped off a dead push mower. It's as basic as they come. It doesn't even have adjustable wheels. The engine was a 3.5 hp Tecumseh (LEV80). It was covered in oil & he claimed it had no spark. I was going to scrap it but it had excellent compression.
I changed the crankcase breather (I had a spare), set the pickup and changed the plug. It would run on carb cleaner but nothing more. When I opened the carb, this is what I found.
I was going to soak the carb in CLR but when I got the the store, it was $10 for a jug. On the way out I spotted a cooler full of Coke. A light went on & I picked up a 2 Litre jug of Coke Original. Here is what the carb looked like after 5 days in the stuff.
Then I touched it up with a wire brush (not a wire wheel, just a brush).
I bought a new float (old one leaked), and a carb kit (but only used the needle, seat, and bowl gasket). I thought for sure I'd wasted my time, but it runs.
