Title: Carb pissing out petrol
Post by: elmo on October 03, 2011, 05:09:50 AM

I've read about and it just seems like its the float that causes this.... do you think the float could be stuck or something and thats why petrol pisses out of the overflows?

yep i think you got it. it could be as simple as a carb strip and clean out or it could be a worn out float valve. this pic is a 94  125 carb, as you didn't give model and year but there will very little difference regardless of wot your bike is. the float valve is 16030 on the pic. just click it to enlarge

Ok guys quick brainstorm...

Stripped , inspected, cleaned and rebuilt....

Now what happens is every 20 -30 seconds about 20ml of petrol flows out of one overflow pipe.

I have just put it all back together but have not started her, tomorrow i'll start her and run her for a while to see what happens....

Least it doesnt piss outta there like before i suppose :|
