By "tossed it in there" did you mean you disassembled the float bowl, installed the needle and attached it to the float, set the float level, then reassembled the carb?

When I cranked  it, the RPM ran away, couldn't control it, I cut the ignition off in about 1-2 seconds.

When I looked under the hood, yes, there was gas spilling out of the carb, it probably would have choked itself to a stop from way too much gas if i'd let it run longer, I just didn't give it a chance.

But the point being the car will start,  if it's a quick starting engine, even if there is completely no control of the fuel coming into the carb float bowl.   But the RPM will instantly climb and you won't be able to stop it, except by killing the ignition.

The difference being most of my AMC engines started very easy, ( just shake the keys at it,  as they say )  no long cranking period unless it was very cold.

It wound up being the issue. The new carb did not come with the piece only the gasket, but when it was out it revved up to the point of almost grenading. The next day when I got out of work I pulled off the line before the float chamber and tossed it in there, wound up working just fine now.

 I have had a brass carb. float that had a hole in it, it sunk to the bottom of the float bowl and wouldn't close the needle valve .  Engine RPM went very high instantly.   Had to shut the engine down.
Finally figured out what the cause was.  Different exact cause,  but the same effect.

We all make mistakes, that's how we learn.



leaving the needle out will NOT cause a fast idle but it WILL let the gas out all over the place IF it runs at all....

No problem. Respect of young people in the classic car hobby is a big soap box of mine. 

Do you know the most common reason for why people put others down? For why they insult others? It's because they are insecure about themselves, or more specifically are insecure about how they are seen within a group of people. They are worried about their "status" within that group. They see a newcomer, a younger person, a weaker person, or a more ignorant person as an opportunity to prove they are of a higher status. They insult that person to make that person look weaker while making themselves look stronger.

It's very masculine and caveman. Competitive. Primal. The males of almost all species do it. They compete for status and respect. The young ram wants status, the old ram wants to defend it, so they see each other as threats and fight. The weak are seen as easy targets to demonstrate one's status. Human men do it too. Especially online. Especially in car groups. Most wars and atrocities can be traced to this. "We are strong, they are weak, let's go kill them and take their property." 

We must resist that. Especially if we want young people to join us. We must find ways to be secure in ourselves and not see others as a threat or competition. If we do that, there is no reason to insult others or put them down. Everybody is happier. 

I think the entire world would benefit from that.

Fighting that for years has made me bitter and resentful, which is why I made my snappy remark at him. I became that which I hate: I became an angry bitter car guy holding another car guys' age or inexperience against them. I HATE when people do that to me, and I was a total hypocrite to do that someone else. Sometimes I need a reminder that another young person in the classic car hobby is not my enemy or competitor. They are my ally against true enemies and competitors. 

Sorry for that, Brad2192. I am glad you figured it out on your own and stood up for yourself. 



That was probably the coolest dung I've ever heard come from anyone. Thanks for the apology, like everyone said that is some real-man action to do what you just did, made the whole post worth it.

It takes a man to admit a mistake. I responded like I did because I knew that a young guy had no way of knowing about carburetors like people my age do. We should welcome young people into the hobby. I know very little about tech gadgets, but I am familiar with carburetors due to my age. Thanks for posting this. I respect that.

FSjunkie, you're --> 23 <-- ? oh boy, OPEN SEASON! HORRIBLE YOUNG PERSON! heh heh! lol

i thought  you were older. that could be flattery or an insult. YOU DECIDE.

yeah, it seems most car folk (dangerous generalizing...) go for nostalgia. young people making mistakes doesn't fit into that. i don't really understand nostalgia, i didn't get that gene. ugh, i don't want what i had before, i wanna do new things (sometimes with old stuff, eg. cars, cuz they're hackable. i add software.) i feel like i mostly make mistakes. i have piles of them. just installed my 7th (seventh) instrument panel today). 

i did far dumber stuff, and persisted at it, than just mis-identifying a stupid needle valve. but it was pre-internet, so fewer witnesses.

also, the culture then was a lot more comfortable with the logic of physical stuff, physical problem-solving. today, "kids" (lol) all of the goods, and all of the metaphors, are software constructs. in the 70's, old guys complained that kids were playing with computers instead of radios/electronics, as $DIETY intended. today, it's all clicking on corporate-managed phone-product.

owed fokes should FKN CELEBRATE "young people" messing with physical, actual technology -- it's much harder now for very many reasons including there's simply less of it to mess with.
