Re: carb leaking gas, what did I do wrong?
Ok, that will be my next task.
EDIT: Ah ha! I just removed the carb off the car and pulled out the float and gave it a shake... sure enough, it's full of gas! I wiped it dry and I can see gas seep out immediately... I guess a new float is in order! At least I now know what the culprit is. (probably could've found it a lot sooner but I'm still learning so always afraid of taking things apart and risk making it worse, or not being able to put it back together correctly.) Thanks everyone! Last edited by jason78613; 03-04-2021 at 12:13 PM. |

Floats, like people can be prone to have gas!

Re: carb leaking gas, what did I do wrong?
I was really hoping to attend a car show happening this Sat... would it be a good idea to drill a tiny hole in the float (just to get the gas out), then patch it up with some gas tank repair epoxy like this one?
https://www.autozone.com/sealants-gl...it/698473_0_0? At least as a temporary solution until the new float arrives? |

Re: carb leaking gas, what did I do wrong?
Jason,
I know MAX and I know he'll do you right. By the way do not submerge the float in hot water....luke warm is sufficient....hats off to '51 MERC -CT J B Weld is good stuff but in this situation I would not do it.

Do the water test to locate the hole and attempt to solder it? But use warm water NOT hot as to not cause the fuel inside to expand and Explode! Once the pin hole is located, drill it out with the tiniest drill bit you got to drain the fuel before soldering. Re check again after repair to ensure its sealed.

(don't apply air pressure to the float). You can tell if the evaporation is sufficient by smelling it. Then it's just a matter of soldering to seal. Have done several in this manner with success.

Re: carb leaking gas, what did I do wrong?
Just tuned in to all of this; been off doing taxes preparing for my CPA (Cleaning, Pressing and Alterations!) for nearly a week...
New float, pin and gaskets headed for Texas in 15 minutes. Did I say I'm sorry.

Re: carb leaking gas, what did I do wrong?
This truly is an awesome forum! With all the help and additional searches through previous posts, I feel like I got a solid crash course in carburetors!
As Max mentioned, he reached out and will be sending a new float, much appreciated! As for the car show this weekend, I followed Will D's instructions and drained the gas through tiny drilled holes and then soldered them up. Then did the hot water test and no bubbles! Took a test drive and it runs fine (I think I just need to adjust the idle screws to get a smoother ride). I don’t trust my soldering skills 100% so this is definitely a temporary solution until Max’s new float arrives. Thank you so much to everyone! |

Re: carb leaking gas, what did I do wrong?
And ladies and gentlemen, this is why you use the incredibly awesome vendors who populate this forum.
Over the last dozen years I've got experience with Uncle Max taking a very stinky leaking filthy carb and making it showroom for my '35. And Charlie has his fingerprints all over my '36 Phaeton (trans, rear, carb, steering, FP, and more). They are very high on the list of people who get my business so I can get back to driving and smiling! Their messages here are totally typical of how they handle things.

Re: carb leaking gas, what did I do wrong?
float level or pump pressure out of curiosity did you run the eng around 1500 rpm have seen fuel pump pressure climb dramatically above 1000 rpm
