First off, let me say that this forum has been so enjoyable to me, as I know just enough mechanics to be dangerous. Being able to search forums by topic has allowed me to tackle a lot of tasks, I would never have attempted, so thanks for all you who share your experience and expertise.
My question, it has become evident that my carb is leaking gas, and its enough that I have quit driving it for fear of burning my truck up. from what I can tell, it appears to be a stock carb. It has some markings on the side
What is the rough cost of having this rebuilt, and given that there have to be improvements in the last 45 years, is replacing it a better option? as for the swapping it out option, Is it something a dude who is mechanically inclined, but a basically motor illiterate can do?
FWIW- this is going to be a week-end driver, not a "preformance vehicle", I'm in the process of bring it back to Original as much as possible.
You can do it yourself if you can turn a wrench or screwdriver. One of the easiest carbs to rebuild you'll find.If you decide to do it yourself, folks here will help.
I can usually rebuild one in an hour but i have done it before. I found this primer on the internet that may help you. Make sure you blast out all the small passages with a can of carb cleaner.
Yep, just rebuild it yourself. Its very expensive to replace the carb when you can just rebuild it for around $20 and get the same result.
The most important thing is buy two or three cans of the spray type carb cleaner and take it apart and clean it up really good. My carb leaked gas too. every time i pressed the gas it squirted gas on the intake manifold. I bought a rebuild kit for $20 at napa and it works like new. Its pretty easy to do, but take your time and take note of where everything goes.
The only thing I screwed up on was I didn't clip the float in place properly, which cause it to shoot gas all over the engine (it literally shot 6'' strait up from the carb all over the engine.) that was an easy fix though, it just too a while to figure out why.
anyway, just rebuild it
PS- there is a metal tag with numbers and letters what is bolted on the carb. Mine was covered with goop, just like your probably is. Thats what you need to take to the auto store to get a rebuild kit.
These covers are usually bowed between the screw holes, but you can take a punch with a 3/4" wide blade and tap it flat on a hard surface. I have to do it everytime I rebuild one of these carbs.
You are missing this little rubber plug in pic and the bowl float is probably set a bit too high. that'a where the gas is coming from.
Very easy to rebuild. Bah, go to Autozone and get a kit for your Autolite 2100
carb $14. it's the only 2V kit for that brand they have, can't go wrong.
Cake!
The step by step in post #5 is a pretty good guide.
Having a manual choke makes it that much easier.
GS, I'm not particularly gifted as a mechanic, but I used the NAPA kit, which comes with instructions as I remember, and is pretty cheap (less than $20?). The recommended "professional" I took it to 12 years ago was no better, probably worse, than me. I took my time, and completed the rebuild pretty quickly one afternoon between smoking cigs and watching TV. Most time was spent cleaning, and pay attention to that little ball thing. So, adding to the general chorus, do it yourself, for sure. Good luck, have fun.
Alright Gents, You have convinced me that I can do this. I will forward your names and home addresses to my wife (for retribution purposes) in the event that the truck becomes a useless piece of lawn furniture! To Autozone!
Make sure that you soak the body in carb cleaner overnight to get all the accumulated crap out of it. I didn't do that and had a poor performing carb that I eventually had to rebuild again. Since you are asking the questions, you are prolly smarter than me. It is not a hard job. Good luck.
