Carburetor problem

I was smelling fuel past couple days in my newly acquired chevelle. Found dripping fuel at filter housing side of carb. Turns out last time someone changed filter cross threaded fitting into carb. Thus stripping threads in carb. Now i can't tighten and gas is poring out. Think i have a big problem. Not to happy right now

I've never seen one but i will look into it thanks. If I can get this dried up think I may just put an inline filter and never fool with that again well as much as possible

Re: Carburetor problem

What carburetor? You may be able to just buy a part to replace the one with the stripped threads?

Re: Carburetor problem

Quadrajetparts.com and I'm assuming it is a Q Jet because that isn't uncommon.

Re: Carburetor problem

This is what I have done since 1970. New filter in the Q-Jet. The same DAY install a metal fuel filter at the tank. I change the filters at the tank. Because I am older than DIRT! I have learned to keep my fingers and wrenches away from the fuel line AND the filter in a Q-Jet.
WHY?....... After a few rounded off flair fittings and some stripped threads in the Q-Jet housing. Well to keep from using VERY bad language and wanting to kick your dog.
I would install a filter at the tank. A good METAL filter, NOT the pretty see through plastic or glass. Also a METAL line from the fuel pump to the Q-Jet.
PLEASE NO rubber hoses.
Hey NOW,,,,,,, Do what you want, Its your car. The above idea has worked well for me for over 49 years with Q-Jets.

Re: Carburetor problem

What Robin said.

Quadrajet parts can repair the inlet threads along with a couple other shops. It's an operation performed in a mill with a very large tap. The install a Heli-Coil which is hard steel and will last forever.

The Carb Shop can also do this competently.

Re: Carburetor problem

warning. self-tapping fixit parts often end up crooked and leak. they also carve a LOT of metal out of the inlet and may ruin it permanently.

Pay your money and take your chances. I'd go to one of the shops listed, send them the whole carb and ask for a basic rebuild

Re: Carburetor problem

Sauce,

Please fill out your profile info so we can know you a little.

Is your carb the original? give us the year of your car and the number that's stamped vertically on the drivers side just above the secondary throttle shaft.

Re: Carburetor problem

Ok before I get totally slammed for this recommendation I need to make one thing clear. This is a very workable and low cost solution. Also my nickname a few years back was Carburetor Bill so bear with me. Rochesters love to strip out at the fuel inlet and when I was rebuilding carbs good spares were readily available and changing the main body was always my first choice to fix this problem. However if dollars really mattered and the customer couldn't afford that route or wanted to keep the carb # I would remove the filter and spring, coat the threads with Marinetex and lightly thread it back in. I would tell them to add a inline filter somewhere inconspicaple, This stuff can be tapped, is strong (10,000 PSI) is impervious to fuel and almost resistant to any chemical out there. Its great stuff and can fix almost anything and sticks to anything. Here is a thing a buddy of mine did up here with his 25 foot boat, he cracked a ring and scored his cylinder pretty bad but he had to get it running immediately. He filled the score and did a quick hone, put on a new ring and put it back together, The next season he took it apart to fix it correctly but the fill held so he said screw it and put the head back on. Ran it like that for two more years when he finally did a total rebuild. Sorry for the long post but its an interesting story, at least IMO.
