Gas in air filter?

I've finally gotten started on the overhaul of my FREE '79 Indian AMI-50 4-stroke. (dances lucky dance)

I'm new to mopeds (mostly cuz I never had money for one) but I have a pretty decent working knowledge of combustion engines and 2-wheeled vehicles.

So I take my air filter out of its little cubby -- and it's soaked with gasoline. (hasn't been run in 15 years). The carb (keihin) was clean and clear, I see no obvious blockages of any kind, the working bits all move correctly and whatnot.

Logically, the gas and air both go into the carb (fuel line and intake thingamajic from the tank were both clean and functioning.) Something must be stopping it after the carb, right?

IT's not in my troubleshooting guide. Help!

Pygmy,

You may want to give a little more info. Little thing like, does it run and if so, how well?

Anyway, check the carb overflow, it nust have one, and figure out if a flooded carb would cauuse gas to run into the filter. Then disconnect the gas line from the carb and make sure the petcock works.

I was running to work (late) and hurrying a little on that post.

No, it doesn't run...yet. It seems to be in relatively good shape, but I got it from a lady who knew only that it was green and didn't work.

The carb overflow (the small tube going out from the carb and not connected to anything else, right?) goes straight down the body and nowhere near the air filter. The way it's set up, it doesn't seem logical (with gravity and whatnot) that gas would be able to get* to the air filter intake part of the carb without flipping the whole thing upside-down.

I'm sorry if I'm not entirely clear, this is my first moped and I know enough about combustion engines and bikes, but I've no experience with these (plus mine is kinda weird, being a four-stroke, American-named, Italian-built, lotsa Japanese parts conglomeration).

It looks to have had a minor dump on the right side (carb and air filter on left side). If that was possibly the last time it was run (engine kill switch is broken off...) ...

I don't know. I'm basically taking it apart and cleaning it and replacing plug, battery, fuel line, et cetera. When I get all that accomplished, I'll find out of it runs or not -- hopefully enough that I can trace a problem somewhere.

I wanted to know (since I lack the experience) if gas in the air filter was indicative of a specific problem or what.

It usually means that either the float is sticking, or the the petcock isn't working correctly. Your best bet is to put new gas in the tank, and clean the petcock and carb thoroughly. :)

Chris is as close to right as you are going too get. Go ahead and clean it up like you planned.
