Crap in Gas Tank :-( By tydow (Read 1,010 times)

Hello,

Today I took a look in my scooter's gas tank and saw a bunch of brown thick crap. Anyway to clean this out without removing the gas tank? I tried searching the board for help before asking with no luck.

Thanks

Try pouring a big bottle of rubbing alcohol into the empty tank. Slosh around, let it sit a while, repeat several times, drain. Ethyl alcohol is a lot smaller molecule than the gasoline hydrocarbon so it's a better solvent. So just because the gas in the tank didn't clean out the crud doesn't mean you can't get it out. Rich

Hello,

Thanks so much for your help. I am thinking all of that crap in the tank is just old gas gone bad. When we put new gas in the tank, it started to drain from the bottom of the scooter. The drain screw is still in there. We tried to tighten it up but it still leaks gas. Guessing we need a new drain screw. Just our luck.

Drain screw where on the float bowl?..you could jut be missing a screw..they tend to fall out..it is a 6 mm metric fine

But if you have varnish in your tank, chances are it is in the carb..so try running it, but if it doesn't start you need to take off the float bowl and clean the carb and run fine wires through the jets and small passages...carb clener will help, but you need to physically clean the carb well, and change the fuel filter...use one designed for gravity feed system, not a car...
