Newly Rebuilt Carb. overflowing gas out the top......

I just finished rebuilding my first Rodchester one barel. I started the truck and gas pored out the top, The truck runs like I have it to the floor. Could this be the Idler screw, My first carb rebuild

 

I would look at the float/needle and seat area. No help from idle screw

 

The nedle and seat is letting too much fuel in. Could be just a piece of dirt, or the float is too high, or the float has sunk, or...

 

float is sticking down or sinking because it has hole in it.

 

+1 It sounds like your float is not adjusted correctly.

 

Bent or stuck float. Or installed upside down? Did you compare all parts before installing. Did you check float drop?

 

Would there be a HOLE or a pin-hole, everything good good when I took it apart.

 

I could Have intalled it up sidedown I go back and get a "do over" the gas runs out very fast after I shut it down....

 

as I mentioned in your other Post Change you oil Now since you have Gas in youe Oil
also Follow the Directions when Rebuilding the Carb
unless you are a Master in Rebuilding Carbs
just my 3 cents

 

Same thing happened to me when I rebuilt my first 2GC carb. Float was to
high.

 

......I left the gasket off the needle seat once.....another time I left the needle out.......

 

There's no way to say this and be gentle:
"How do you do something you don't know how to do? Don't do it."

 

I disagree. Doing is the best way to learn. I'm sure this dude's 2nd and 3rd carb rebuilds will go much smoother and he will take away a wealth of knowledge from this experience.

 

I disagree also. After my first carb rebuild, they all went much better. If you are told not to experiment or Discover for yourself how to do things, then why even get up in the morning. The satisfaction of doing something by yourself is energizing. Congrats on the carb build mx6262, Bravo that you even wanted to try it. I applaud your efforts. Send pics of the truck if you can.

 

Ya leave the guy alone. he has to learn somehow. You, at some point in your life, didn't know how to drive, right....

 

he didn't know enough to use the bathroom, either.

 

the float could have a pin hole, so small that you cant even get gas to run out of it but its in there, you can tell by shaking it, it will feel like theres a weight inside moving around, just had a new model-a float do the same thing was fine for a week or so then it sank, replaced it with an old one and she's fine now, i bet your needle and seat is just stuck a little, give it a few lite taps with a hammer while its running, outside your shop would be a safe idea.

 

So how is life going for you, still crawling and having momma change your diaper?

 

also your throttle must be open for the motor to rev up, if it was closed it would stall from all the extra gas.

 

I had a problem with the float in my Rochester B getting hung up on the sides of the bowl occasionally causing fuel to leak out of the top, so make sure the float travels freely for its entire throw. And, of course, double check the needle and seat, float height, etc.

 

If you don't do things you don't know you'll never learn anything. Haven't you done anything you didn't know how to do?
