Greetings all. I am a newbie to the GMC motorhome club. I have a 1976 Eleganza II. I purchased it to make some great memories with my wife and children.
Here's what is going on. It seems to be flooding as I drive, especially on hills and curvy roads. I replaced the needle valve and seat in the carb, and checked the float and it still floods on occasion. Once while it was flooding badly and the fuel was boiling in the carb someone suggested I loosen the gas cap. When I did, gas and gas-vapor shot out. So I have begun running it with the cap loose. Even then the engine will occasionally stall (which I assume is due to flooding still). I wait about 5 minutes and put the gas pedal to the floor and it will eventually start.
Here are my questions:
1. Does this sound like the carb is in trouble? If so, who works on these quadrajets? I have talked to 4 mechanics in the area and nobody wants to deal with it. I found one who suggested to put a Edelbrock on it since it's simpler....Any suggestions?
2. Assuming that my vent tubes are clogging somewhere I feel like I should drop the tanks and go ahead and replace all the vent lines. Or perhaps there is an easier fix, maybe just replacing the canister up front. Where can I buy a new canister and do I need to replace the vapor separator at the rear tire?
I would appreciate any advice in tackling this.
Thanks
