Petrol Leak

[euanryan]

Hi there, i'm new to the forum and new to the world of minidirt biking.
I bought off ebay a rebo mini dirt bike for messing around on.
Its a 2 stroke 47cc.
I had it running fine and it worked great. But one afternoon i was riding it with some mates and i noticed petrol leaking from the underside of the engine
It was dripping out from a pink rubber pipe that i assume is an over flow pipe.
I think the engine has flooded.
But what i don't know is why the engine has flooded
I'm not very technical when it comes to motorbikes but i have been told its somthing to do with the float getting stuck

I don't know what this means but i am willing to try to fix it.
What i need to know is if this is what has happened, and how to fix it

Thanks

Euan

hey
look on ebay for a pullstart carby theyre really cheap and theyre alot better than the 1s that u get stock its alot easier to buy new 1 than it is to relevel ur floats im pretty sure u can buy the carbys in groups of 3 off ebay for quite cheap im not quite sure how to do the flaots all i no is theyve got to be exactly level or itll dump ur fuel cheers mate good luck

If your in the UK then yeah that should be fine

 

[euanryan]

yeah i'm in the uk, thanks for your help

 

[euanryan]

is there any special way of fitting the carb?
or is it just the case that i just fit it as the old one was fitted?

thanks

 

[liljohn_92]

just unbolt ur old 1 and this i should go on exactly the same way utr old 1 came of

 

[unitrider08]

between your fuel tap and choke is where it comes unbolted its only a small part on small engine thus making the 2 almost side by side so yea its not hard i had to redo myn yesterday after 9 and a half hours of straight riding only stopping in at servo for fuel and lunch few times

 

[euanryan]

right i've fitted the new carb and it works!

but, and there is always a but , The bike only starts if i'm holding the throttle open a tiny bit, and if i stop twisting the throttle it cuts out

any idea why this is happening and how to fix it?

thanks

 

[liljohn_92]

adjust your idle screw a bit till u get it right

 

[euanryan]

possibly a stupid question but, whats an idle screw?

 

[euanryan]

anyone know?

thanks

Its the screw in the side of the carb that lifts the slides stop position therefore increasing idle speed

 

[euanryan]

well got my new carby working, then snapped the pull chord

new one is on its way

 

[euanryan]

got the bike running great now, thanks to all who helped
