The nuts act as an aggregate to loosen the sludge. The acetone rinses the lacquer thinner's residue.

Berryman's B12 is a good carb cleaner in spray form, also comes in liquid. Dont get it on paint or rubber!
Let it soak, shake it daily, let it soak on a different surface, repeat as necessary!

The tank can be cleaned out as the previous guy said. That works! Check for rust in there too. If it's rusted badly I honestly don't know how to fix that.

But heres what I did with the tank on my '87 TRX250. It had rusted so badly, from sitting empty, it had holes. A Honda replacement tank ran about $400.00, money I didnt have!
So I removed the tank, cut it into 4 pieces with a Sawzall, fiberglassed the inside of each piece, wrapping the glass about 2 inches over the cut edges to the exterior.
After it dried and I examined it extremely thoroughly for pinholes and repaired them, I sanded the glass on the exterior, placed the pieces together and glassed them in position.
I painted the tank with cheap black paint and put some fuel in. If there was a leak, the gas would wask off the paint and pinpoint the defect. There were only 2 pinholes!
I made these repairs 10 years ago, they are still holding up fine! Sure, I lost a little tank capacity, but it was well worth the savings. With the tank mostly hidden by plastic shrouds, it didnt have to look perfect, but could have with a little more time
If a replacement tank is too expensive or non-existent, maybe fiberglass is an option.
