You will probably get a carburetor for a Chevrolet P-30. There was no such thing as a domestic Chevrolet Motorhome. I understand that some GMC Motorhomes were relabled for the export market.

Needs a check on the casting number. Wrong number equals wrong carb.

Well you are the first of 2 to fall into my trap and you are not alone. My point in posting this was is what is wrong with the GMCNET and the typical old crows that without any knowledge dismiss issues that the rest of us 8000 GMC owners can benefit from. I purchased one of these and the part number was correct and specific to the GMC only, unlike what you immediately dismissed. I put it on my coach and it performed perfectly--I didn't even need to set the idle adjustment. I consider my coach one of the few un-molested coaches out there since it was restored by GM while I was still there. Then I took it off and my retired GM Rochester Carb engineers and I took it apart. It has every spring and part per the original drawings. If I had left this post up longer you would have had nother 20 nay-sayers who for some reason have the arrogance to dismiss anything that doesn't fit in with your misguided judgement. I recall a few years ago that my good friend and retired Rochester Engineer was blatantly told that he didn't know what he was talking about. He no longer particpates on the GMCNET but I guess the old establishment survives. I wanted to leave this up for another day or so but most of us know who the judgemental old crows are. It's a shame that new and younger people get mis-informed.

A bit of explanation would help. I see a carb built much later for a non
olds motor, I didn't say anything, but I wondered why it was posted.

But Bob... the way it's advertised? "Chevy Motorhome"??
Who wouldn't suspect it of being just another off-the-shelf Q-jet that
has been cleaned up and rebuilt? No way in hell I would expect it to be
a GMC carb unless someone like you told me it was.
You did indeed set a trap but it was kind of unfair.
I almost wrote and suggested that you can't trust these thing - but I
knew I didn't have to. I let another dozen guys do it for me. :^)
Cheers!

Well not really. It came up on my screen as a 403 GMC motorhome and hopefully we are astute enough to look at the part number. My point is that almost always there is a negative response to things that we all know how to research if we want to. There isn't a person on this net that can't dig one layer deeper if thay wanted to. Personally I think this is a great find that popped up instantly as a 1978 GMC 403 motorhome carburetor--what am I missing???. Everyone on here that was critical knows that the GMC had either a 455 or a 403 engine. Even then, why are the responses negative and dismissal rather than "let's dig a little deeper" If indeed we were a helpfull group, the responses would ask a few more questions rather than say it is the wrong part. The description and pictures show it is indeed the right part that even a 10 year old can read.

No it isn't Dan but finally someone asked a great question. I think that most people missed my point on all this. By all accounts the GMC carburetor is specific and many people covet the ability to get the right one for the year and engine model. There are about 8000 GMC's still out there and I'm guessing there are about 450 GMCNET folks that are dominated by maybe 20 strong people. My thinking was that the ability to get a totally correct carburetor would be a good thing. I expected questions like yours and others like "how do you know it is exactly the right one", is it a good price, is there a core charge?, what did you think about the rebuild quality?, is it identical to the original?, are you happy with it? I knew I would get the typical negative responses like this is the wrong one or this is shit. Dan, you are one of my friends and frankly I don't know why this happens when there is so much positive energy to share. Many times people ask a simple question and in return all they get is non helpfull opinion. I know I'm a rebel. I think it may be time to let the establishment feed itself and create a new forum for people who truly want to learn and share positive issues rather than self serving opimions..

Any information that you can point me to with regards to original carb internal part number configurations would be appreciated. I have found at least one parts list -- but without explanations to the differences between the versions.
Background -- A couple of years ago I tried to measure all the ports and passages, along with the metering rods and springs in a non-motorhome carb which was on my coach so I could have a base line for comparison if/when I got the correct # unit. I also made some changes to the carb -- it was a factory replacement for a 455 Toronado -- altering, among other things, the power spring and the jet sizes. Cliff Ruggles book was my guide.
Well, that coach has been sold and I now have a correct number carb and plan to do a similar breakdown. It is a longer term project among all my GMC to-dos.
Toby Maki (where is he lately?) had also undertaken a similar task -- but we have not emialed in some time.

Speaking of carburetors...
I've got what i'm pretty sure is the original carburetor installed, and it
works great- until the engine comes up to temperature.
then, as it approaches a stable temp, first i start getting micro
detonations in the tailpipe, then the RPMs drop and it lugs, and then it
stalls. Gasoline can be heard dripping into the manifold upon the
self-induced shutdown, and sizzling on the hot parts.
So I figured i'd do a rebuild, since i'm mechanically inclined enough to
follow the instructions in the service manual.
To that end, I got this rebuild kit from O'Reilly:
http://www.oreillyauto.com/site/c/detail/WLK0/151034/02447.oap
I've not opened it yet. According to O'Reilly's Compatability chart, it is
compatible with a number of vehicles and engines, like El Dorados with the
500, and Toronados (and other Oldses) with 455s
Any incompatabilities to watch out for, do you think, or will I be just
fine?

I agree with John.
If you lookup the buyer relleumt you will find he has 1718 feedbacks indicating he has a fair amount of "knowledge" regarding buying

Patrick,
Before tearing into that apparently well-performing carburetor, I'd check
the intake manifold. While I've never heard quite the symptoms you
described, it sounds to me as if they could be the result of floor cracks
in a manifold without the crossover filled: When the manifold heats up,
the crack opens allowing exhaust gases to be sucked into the intake runner,
upsetting the A/F ratio. With the manifold hot, the carb gets hot, the
fuel boils, and you hear it sizzling on the hot bottom of the "riser".
After you remove the carburetor, shine a bright light down the throats of
the manifold. If there are carbon deposits down there, the manifold is
almost certainly cracked. If not, look carefully for horizontal cracks.
You'll probably have some vertical ones between the throats -- don't worry
about those.
If you do find cracks, you can find lots of references in the archive as to
how to repair them -- or ask here for reiteration.
If you don't find cracks, then MAYBE proceed with the carb rebuild (but I
don't think it will help).
JWID,

Sir: it sounds like yout welch plugs in the bottom of the float bowl might be leaking and/or the float needle leaking.

You may want to look here for info on rebuilding the carb and checking the plugs Chuck has mentioned.

Speaking of carburetors...
I've got what i'm pretty sure is the original carburetor installed, and it
works great- until the engine comes up to temperature.
then, as it approaches a stable temp, first i start getting micro
detonations in the tailpipe, then the RPMs drop and it lugs, and then it
stalls. Gasoline can be heard dripping into the manifold upon the
self-induced shutdown, and sizzling on the hot parts.
So I figured i'd do a rebuild, since i'm mechanically inclined enough to
follow the instructions in the service manual.
To that end, I got this rebuild kit from O'Reilly:
http://www.oreillyauto.com/site/c/detail/WLK0/151034/02447.oap
I've not opened it yet. According to O'Reilly's Compatability chart, it is
compatible with a number of vehicles and engines, like El Dorados with the
500, and Toronados (and other Oldses) with 455s
Any incompatabilities to watch out for, do you think, or will I be just
fine?
