How to clean out a rusty gas tank and replace oil on a moped

I did this at TechShop Menlo Park. http://www.techshop.com

I have a 1978 Sachs moped that I finally got to work. It's 2 stroke motor was frozen so my friend rebuilt it. Now its time to clean out the rusty gas tank and replace the oil so I can get on the road.

About 2 cups of thinner swished around the tank got the grime and rust out. Then the tank got installed back onto the moped.

Hail, fellow moped rider! Thanks for the info--I own an '85 Tomos myself, and this info will be handy to keep in my head!
