Carb question

Well went to get in my truck this morning and tried to start it and smelled gas. Took the breather off and re started and gas came out the vent tube like a water fountian. Yestrday ran great today gas spraying. Its a Holley 4 barrell. I took off the bowl and the needle seemed to move (not to say its not broke) and the float was moving freely (not to say thats not broke) and tried again and the gas went everywhere again.

Is the float to move that freely? Maybe the needle is just worn out and when the gas starts into the carb the needle sticks to the top from the pressure. This is something I think has been coming sicne a couple of months ago I went to step on it and the truck dies and wouldnt stay started for 10 minutes., Then came around and was ok for awhile.

Whats your experience? Hole in float?

Well it can be a hole in the float and just letting the gas flow or it could be ( depending on the brand of carb) the spring that holds the float could be broken and letting the float fall away from holding the needle in place, and it could be the needle is working part way and maybe hanging up and not letting it seat and shut off the flow of gas.................Kid

hey so youre a member now huh...cool deal

Well it wasnt that bad this morning weather wise. No the gas is shooting in the air like a geizer from the vent tube. I bet I lost 1/2 gallon trying to start it this morning.

How much is a flot suppose to move? Mine was moving really freely. I may just get new floats and needles in case

Definitily either a float or seat issue. An old trick is to remove the carb turn upside down and shake the shite out of it.Will work more times than you think

also sometimes you can remove the adjustment screws, clean and reinstall.
only takes a speck of dirt to mess things up.

The float adjustment screws or the air mix screw? The ones with the spring?

Well since its nice to put what the problem is after the problem was found so the problem with mine which was making fuel shoot out of the fuel vent tube was a float full of fuel.

Im doing a rebuild anyway sicne I already took the carb off but in the future if anyone has this problem check your floats and make sure they are not full of gas. I could have fixed this right there on the spot but oh well. Full rebuild cant hurt...i hope.
