Pretty unlikely. You would have to put the tank under water to get a good amount of water in.

Dont be fooled...maybe not from one day but I have very good experience of water in fuel!!

I had water coming in through the sender unit gaskets..I thought I had a hole in my tank judging by the amount of water in there but it was only surface water running off.

Striped the carb and drained the filter bowl new fuel in and it fired right up. Wen u pull the fuel line off wen engine is running should the filter bowl empty as well

I would think the filter bowl should be full! Did you catch the fuel you drained to look for water? I have come across many petrol engines of all sorts which have conked because of water, usually needs a filter change and the tank draining too!

I would recommend a good water separating fuel filter. One of the types that uses a spin on filter for easy replacement. Clean fuel is important to the small jet sizes, and water when used in small amounts does a great job of cleaning the carbon out, but as you found out too much water and it doesn't run at all.

Probably not. Most (smaller) motors have a dry-break quick disconnect type connection between fuel line and motor. Pulling the fuel line causes a valve to close on the end of the fuel line and the motor connector; the motor will run until a vaccuum forms, then quit.

Agree with Peter_C if you have somewhere that you can bolt it on to. Drain the tank for piece of mind, then you know that all is well and shouldn't suffer the same problem again
