BR 400 blower leaking gas like a sieve

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
 
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.
