Carburetor Rebuild , Top Gasket Printout / Other Gasket Info
First off, I always wondered why my carbs would ---- up so badly, it only happens to me on the Honda carbs, never on anything else. Well, I tried fixing my carb to no avail so I got frustrated and went to a dismantler and bought a carb ($75 w/ 30 day return policy damn it, the price for peace of mind) and the guy told me that if my carb gets flipped upside down it won't work. I was like Holy shit, why couldn't anyone tell me this before???????? I thought it only happened on those CCVC carbs
So this is my warning to you: never let your carb flip upside down, that includes rebuilding. It won't work!
Another thing, he said to check the first 4 #s on the little tag on the back, he said if it didn't match my origninal to bring it back because honda made about 7 variations of the carb. I know there were SLIGHT differences among them but I didn't know there were 7 of them. I couldn't match the numbers cuz the tag fell off my original but I put this carb in and it works (for longer than the previous I hope!!!)
Don't flip your carb!!!!

Even in the chiltons book they didn't flip the carb... the just held it at and angle... but that could have stemed from the fear of previous honda carbs.

It's called the " throttle stop screw ".
head gasket or carb gasket?
I was just pondering how many three geez were sent to the junkyard ,thinking the head gasket was blown, when it was that o ring gasket at the base of the carb. that small odd gasket is the only thing keeping pressurized coolant from being sucked into the secondaries on the carb. coolant flows through a small temp controlled valve bolted to the bottom of the intake,then from there into the connector at the carb base. it then goes through a passage in the carb,and flows out through the carb base into the manifold,where it joins the coolant also flowing through the manifold. . there is nothing between this passage and the secondary carb port,but a small o ring type gasket. if that gasket goes,pressurized coolant will be sucked under vacume into the manifold,and you are spraying for mosquitios. and most mechanics think the car blew a head gasket. the gasket is cheap,just a lot of work to pull the carb,and replace it. if you ever think you blew a head gasket, disconnect the coolant hose at the base of the carb,and plug it, then take the hose feeding coolant into the intake manifold, disconnect it,and connect it to the outlet hose of the manifold. in other words bypass coolant from going into the manifold. if your steam clears up in a few minutes, you've found the problem,.

thats good advice there :thumbup:
Re: head gasket or carb gasket?
yea this needs to be a sticky it might save some cars from being turned into yoohoo cans.
Re: head gasket or carb gasket?
Made it a sticky.
This is good info honestly.
Re: head gasket or carb gasket?
there are a lot of cars sent to junk or owners ripped off because of things just like this.
In the old days, a modulator valve on a transmission could rupture and suck ATF in the vaccum source... makes the car smoke like the woods are on fire.
On late model Fords, same cooant hose goes thru the intake.
Good information indeed

a rebuilt carb won't have any gunk in it,so don't worry if it gets flipped, the main thing to worry about is an unrebuilt carb letting all the stuff in the bottom of the bowl get loose. i still don't get the cvcc carb not being able to be flipped, i've rebuilt plenty of them and i've worked on them upside down with no problems. i think this is more of an urban legend,probably somebody flipped one,then got garbage in the needle valve or jet, then they think they are all like that.

Maybe someone have a picture of float and needle in from directions shown by green arrows ? Macro mode in camera should be the best...

does masking the fuel pump bleed benefit in anyway??
Re: Carburetor Rebuild , Top Gasket Printout / Other Gasket Info
Never tested it on a stock unmodified carb but my car still ran fine without the hole. If you're worried about doing it just print out the gasket without the bleed and if you notice any ill effects just unmask the bleed. I only assumed it was a bleed and that masking it would allow more fuel to go into the primary.

Is there any way to get the photos back in this thread? I see a lot of captions for some otherwise helpful sounding photos that I could use right now. Having trouble finding the sight glass and adjusting my float
