the reeds are only fully sealed when the engine is running & under compression.
they do not spring shut air tight when the engine is shut off.
fuel can easily get past.
i have sorted this problem out before for plenty of people.

alot of people say their engine is flooded,without properly understanding what it actually means.

try standing your bike on end & see if you can pump any fuel out of the plug hole.

if there is no fuel in there,its not flooded.

so if the piston is at BDC then fuel can just piss through to the bottom end, seems strange?! would it not knacker your big end bearings?

[riky2stroke]

Tdc.not bdc.
Or it could be running through the transfer ports.
It does happen.
You should always turn your fuel off on a 2 stroke when you park your bike up.

Ok cheers for the advice, would the petrol be mixed in with my transmission oil then, could i just drain that instead of tipping it upside down?

[riky2stroke]

no. the fuel cannot get into the transmission side. there is a crank seal to stop this.
the big end on a 2 stroke engine is sealed . you need compression in the bottom end of a 2 stroke or it wont run.

trust me,standing you bike is the easiest way.
either that or remove your cylinder.
i know which i would rather do.

[Acidman]

ok i will give that a go, my engine knowledge is quite limited.
Do you mean having the bike fully upside down?

Will the fuel cause any damage to my bottom end? is this just lubricated by grease?

[riky2stroke]

no.it wont cause any damage.
the petrol will wash some of the lubrication away ,but i wouldn't worry too much. asoon as you get it running again,it will get lubricated.
the 2 stroke oil in the fuel lubricates all the moving parts.

you dont need to have the bike fully upside down.
what i normally do is get someone to help me.
if you hole the front brake on(you could use a zip tie).
then lift the back wheel up as high as you can.you want the bike as vertile as poss.
then with the spark plug out,pump the knickstart a few times to spin the engine over.
if there is a load of fuel in there,it will come pissing out of the plug hole.

its not as hard as it sounds.
when you have the bike lifted up,it will balance quite easily.

i used to have one of those husky wr125's when i was 17.
it was pretty quick after we removed the restrictors out the exhaust.
but the powervalve do brake twice while i had it.

[Acidman]

Thanks buddy, i will do that tonight before i put the new plug in, and hopefully she will fire up!

How did you find the bike?

and how did you know that your powervavle broke did it just run dodgy or not start up etc?

Its the first real two stroke ive owned so ive never really know alot about them.

[Despise]

Dont have time to read all the comments but im sure someone would of answered this.

Take the plug out, drain the carb, fuel tap off, kick it over a dozen times, take the exhaust off or get the bike vertical to drain any fuel in there out.

Then leave the bike over night to dry out (spark plug still out) - quick way is to use a hairdryers or equivalent, get some heat in there to evapourate the excess.

In the mean time, get yourself 2 new spark plugs, that plug will be pretty much dead. Next day or after hairdryer, new plug in, exhaust on, fuel tap on, kick it over, shud fire up after a few

the bike just stopped.
the power valve on the husky's are like suzuki rm's.
they are a pluger type.
the powervalve snapped & totally f**ked up the bore.
& it didnt do the crank any good either.
but i did use to nail it everywhere.
if you take care of it,& dont thrash it permanently,it should be a good reliable bike.

is yours a wr,or an sm?
