Stuck Float?

I foolishly left my TY175 standing for a few more weeks than usual - normally try and fire up every other week.

It normally starts first/second kick no problem at all and always runs really well and cleanly. This time it wouldn't. It fired once but then nothing happened and I looked down and fuel was coming out of the overflow below. 

I'm guessing this is the float stuck? I looked online and the 'quick fix' seems to be to turn off the fuel and put compressed air in this exit overflow. Is that right? There's a small garage in our village with an airline who would do it (they are still open) but I don't want to screw it up. Nor do I massively want to strip the carb if I don't need to.

Any quick pointers? Thanks!

Petrol off, no choke ,kick and see if it'll go.

If not, plug out and kick it a few times, then try again, preferably with a new plug.

Normal practice for me is to tap the float bowl as its filling.

Many thanks both for the advice - much appreciated. b40rt - will try those pointers. And teamferret - I'll avoid that air line (just shows not to blindly follow those youtube 'tips'). Thanks!

Have someone pull and hold the front brake.  

Lift the back wheel up about two feet and then drop it.  

This normally frees up a slightly stuck float.  

If not then you may have to take the carb off and check.

B40rt - many thanks again (and thanks all for various advice - much appreciated). A few sharp taps on the outside of the float bowl. Fired up 2nd kick. Awesome. And so crisp - electronic ignition and a WES tailpipe help big time. Very happy (neighbours maybe less so...)!

You have effected a temporary repair,the kind to enable you to finish a  trial. There is no way I would leave it like that - Something caused the float to stick,most likely will do it again. Nothing worse than a badly maintained bike playing up during a trial.
