I have a Taiwanese 2t 50cc scooter I bought for eighty bucks, it sat motionless outdoors for a year before I got it so the owner was convinced it was a total loss.

The petrol cap doesn't quite keep rain out of the fuel tank (they all do this, if you have a cheap scooter buy a bike cover) so the carb and tank were all packed with sediment. I cleaned out the carb, threw in a fuel filter and flushed the tank half-assedly to get it going. It runs very well and is exceptionally fast for what it is, has chunky tyres that lean like a bike and a good handling balance, so I enjoy riding it and use it nearly every day to visit local suppliers and the corner shop.

Problem is, there's loads of mud hiding in the nooks of the tank so every morning without fail the carb has some water in it. It'll start and idle (pilot jet is above the water line, auto choke functions) but wont accept any throttle (main jet submerged). I cbf draining the carb with a screwdriver every day, especially when the drain screw is all chewed out and rusty.

Correct solution: take the tank out, either find a way to clean out all the mud or just get a replacement.

My solutions:

As soon as it starts up, there's a brief window when you can open the throttle and run it up to fairly high revs and keep it there before water starts making it through the carb. You hear it stop firing when it starts to suck in the water, but if you've brought the revs up enough it clears the water and starts firing again before it can fall all the way to idle and stall; the flywheel effect of the cvt and wheel spinning stop the engine from stalling instantly.

If the above doesn't work (because it's rained heavily the night before or I haven't run the bike for a week), I leave it idling and just lay it down on its side for a few seconds until the water spills out of the carb vent and it's good to go.

I've been doing this for about six months now.
