Had the bike out today, ran it too where we were playing, say 250 yards, set it down to sort out some wee sections, went back, hasn't started since ???

Got home, changed the plug, still not starting :(

Any ideas folks ?

Had the same thing on mine a few years back. right at the start of a trial.

I laid it down flat on it's side until fuel leaked out of the carb, I stood it up and it ran more or less ok for the rest of the trial (a bit fluffy), good enough to get a finish.

When I got home I stripped the carb and got some rubbish out, it ran perfectly once I'd cleaned the carb and put it back on.

If the carb was overflowing, you've probably got something stuck in there.

Make sure you run a real thin wire down through the jets to ensure they are clear. Just looking through them isn't good enough as they can look clear, but have a thin scale of varnish that can still plug them up.

I know this sounds like a dumb question but...there is gas in the tank right? You'd be amazed at how many times guys think they have problems and have just run out of gas.

Another dumb suggestion. Make sure you haven't accidentally turned the gas flow off at the pet cock.

After you get it cleaned up and running, put a little SeaFoam or something like that in the tank and start it up till you're sure it's in the carb between rides. The junk they are calling gas these days has so much crap it that it seems to gum up things a lot quicker than it used too. I've had problems with both of my road bikes with the crappy gas they sell. Good luck.
