gas leaks out of this hole. what is it?

gas slowly but steadily leaks out of this hole on my carb. (see pic)

I don't have an air filter currently--im just gonna get a random one that fits. Is some piece supposed to block this hole normally?

sticky or misadjusted float

is a float a little metal thing that should be sort of 'plugging' that hole?

can I stick a wire up there and fish around?

Re: gas leaks out of this hole. what is it?

no its in the bowl. you might want to read up a little on here about what the components of a float are as some people will call you names if you dont know things on here. just a heads up

you need to make sure your float, in the bowl of the carb floats. if it does, replace your float needle. that is connected to the float. it has a rubber tip on it. if it doesn't float, replace the float.

items 13 is float 14 is the needle

DO NOT BLOCK that hole that is your part of your mix/idle circuit

also.. make sure the pin that holds the float in..is clean and not sticking.

thanks Gruff-,

are you saying that once I check and fix the float & needle, gas will no longer drip out of this hole?

Re: gas leaks out of this hole. what is it?

gas can't get into the carb if the float and float needle work correctly.

if the float and float needle work correctly, you won't have this problem.

bowl fills up pushing float up, needle seals off the gas. = no gas = no drip

hey mattew whered ya get the qt seat cover? your bikes look great

Re: gas leaks out of this hole. what is it?

no problem dude.

looks like a qt50 carb..

replace the bowl gasket while you are ordering stuff. might as well.

and as a tip, and unrelated to your leaking..

get some moldable, gas safe, putty epoxy and plug up the carb drain on the bottom of the carb bowl. push the epoxy putty in there until you know you have enough in there. i have had two qt50s and they both became issues as far as leaking. i have never needed the drain spout.

that was the original seat cover.. it looked nice, but the back was messed up, so i ordered a repalcement on ebay a week or so ago for $27.00. it's on there now. it's a nice cover, but the lettering is kinda fakeish.. but i would say if you need one.. they are way cheaper then the originals.. and if you put one on.. use the shortest staples.. i messed up and didn't know but they poked through around the back base on the side... i replaced the staples.. you cant tell but there are tiny holes.

that pic is old.. two summers ago. i have been modding it up.

new seat cover and all stainless cap head screws now. no footrest covers, k&n filter 2540, boysen reeds (onorder), premix 40:1. oil tank is now part of the gas tank.. new tires, brakes, cables and battery.
