What kind of fitting is used for water under the carb?

It sounds like a plug came out. Can you take a good quality picture and upload it?

I'd have to remove the carb, intake and assoc hoses? Can't get to a spot to take a real good picture. There is a small hose on the underside of the intake but does'nt connect to anything? Is the intake itself water cooled?

Some are, yes, but not usually that far up. Is it definitely water and not fuel?

Yes, it's water, I can put my finger over the hole while running and it'll stop flowing.

Can you tell if it's threaded?

I can't tell, it is a machined hole but not sure if it's threaded.

Can you see any loose hoses anywhere?

Yes, there is a loose hose , but not sure what it comes from or what it goes to, the hose is a water type rubber, small size hose. I had thought it went onto something that had fallen out but don't know what it could have been or where it came out from.

Can you get a picture of it and where it does connect to?
