Do not! I repeat - Do Not buy a rebuilt carb. Instead, have your existing carb rebuilt. Carburetors are very specific to the original configuration and rebuilds are more generic in application. Too much of a crap-shoot to get one that is jetted and configured correctly. Been there - done that - never again. The Q-Jet is also prone to have a warped top horn from Neanderthal mechanics overtightening the top bolts. Causes vacuum leaks and rich running.
Best of luck getting things sorted out.

I had the carb on mine rebuilt last year. Out in California you should not have any problem finding a rebuilder. By getting mine rebuilt and the distributor recurveddistributor recurved it made a world of change power wise.
What's this? how do i do it?
Well, it entails changing the springs and maybe the weights inside of the distributor.
Here is the web site and company that I went to.Clicky He is about a 2 hour drive for me, I took it there and he sent it back. Total cost was about
$125 with shipping. He completely rebuilt it and recurved it. Been very happy with it.
Here is one of many posts that JIM83ITASCA has posted. ( he has since passed away)Clicky

I already checked the fuel is getting to the carb. New fuel pump and filter, I'm going with the rebuild of carburetor as being my solution. It happened all the time not when hot and now it has a terrible time starting. I notice that when i pump the gas, nothing is injected into the carb and while it ran and idle high when cold, it would "diesel" out when I turned it off. Thanks for the input.

Sounds like you're on the right track going with the rebuild. I found the Rochester Q-Jet to be a great carburetor when dialed in properly..
Good luck & Safe Travels...

Check with this place:
Superior Carburetor Service
11005-49th Street North
Clearwater, FL 34622
727/572-7755
They rebuilt all of the carbs on any of the classic cars that I restored. They do accept carbs shipped to them from all over the country and they do great work. A complete rebuild of your carb will cost around $100 and it will come back to you looking like new.

Ok, back to the drawing board as just re-installed my rebuilt carb.
things I've replaced so far.
Changed fuel filter at rail, at carb, new mechanical fuel pump, and rebuilt the carb.
Things I've done:
removed the fuel line at the carb, cranked the motor and it take a few seconds but finally fuel squirts out of the line..
I've gotten under the coach and followed the fuel lines and i see this
to me it looks like a fuel pressure regulator... anyone know?
I'm going to check the rotor cap as suggested and cross my fingers... My summer is almost over and I was hoping to have some fun with her but son far it has been anything but

Thanks for the follow up. I did not know they used a regulator unless there was an electric pump.
