It is called "hydro-locking", happens when an engine is flooded badly.
It cannot compress pure fluid.

Thx Fish....I realise that...but don't understand why after a really thorough draining and drying this happens with such a tiny amount of gas? Should I take it into a repair shop....and if so, what can they do to prevent this happening again?

Try this:
Take the plug out and pull the rope a couple dozen times with sparkplug hole facing down. Put plug back in and do NOT choke it and pull rope a couple times. You should just feel normal compression. Now spray a small amout like a quarter of a second of starting fluid in the carb throat. Hold throttle wide open ad try to start. It should fire up for about a second or so. If it does not fire at all either no spark, low compression, crankcase leak or intake air leak. I don't like putting liquid fuel in the spark plug hole of small 2 strokes. It is not vaporized and it only take a little to wet the plug and hydro lock it.
$0.02 worth.

Hi guys....just to follow up....just got the call from the repair shop.....the crank needs replacing and apparently they are no longer made. Anyone any ideas if a crank from something else would fit?
Thanks

It is still in the price list, but you wouldn't want it.

Thx Fish....sorry .....I didn't ask what exactly was wrong with the crank, but will do when I pick it up.
I was just curious if the crank from a different model would fit, but at that price I guess the blower is toast! Shame, as it's been a great machine and in the last little while I've spent probably $200 on it.....oh well!!

Well, not to say anything about the guys at that shop, but they are probably just trying to get out of working on it.
It is @ 20 years old or so.
