After stressing out and going through three mechanics to solve the stalling, loss of power, inability to adjuts the carb I finally got my kids 1985 d100 Dodge pickup to a guy who knows what he's doing. He pulled the carb, gave it a complete bath, installed the rebuild kit and informed me of what the cause of all the problems were...damn carbon from the emissions canister got sucked up into the carb and fouled the jets. When he saw the carbon he remembered that was a problem years ago when these engines were popular. Funny how no one else suspected that. We will not be reconnecting that canister.

Not an uncommon problem. I haven't run into that for a while and forgot about it.

Just install a in-line fuel filter in the bowl vent hose and the canister purge hose. This will keep the charcoal out of the carby.

Now that you mention it, I recall that happened to my 1987 slant 6 truck but it was so long ago that I forgot about it.
The problem seems to be from mounting the charcoal canister on its side. After a few years of bouncing around on the fender the charcoal pieces wiggle themselves around the screen and filter element in the canister and mysteriously work their way up the bowl vent hose into the carb bowl. I think I remounted a good used canister off of my old Valiant onto the truck and redid the mount so it was standing up. Later on I saw a truck or Ramcharger in the salvage yard that was a bit newer than my truck and it had the canister mounted in a standing up position using a bracket just for the purpose.

On my 1979 Dodge truck I had to install some fuel filters in the hoses between the canister and the carburtor. They are clear plastic filters and they filled up with charcoal but it keeps the stuff out of the carburetor.

In K cars and carvans, Mine (1987 plymouth caravan 2.2L 5220 carb.) has this disk shaped filter between carbon can and the carb's vent nipple.

I hear a lot of complaints and problems right here with stalling, loss of power,and general runability problems with these slant six engines. I posted my problems with the 1985 Dodge D-100 and while I got a lot of suggestions no one came up with this scenaro where the carbon gets sucked up unto the carb. It now seems to me that this would be one of the first places to look for the problem where these symtoms are indicated.

It's not the engine that has such a stalling problem. It's these crappy leaned out way too far Holley Carburetors that they put on them. The stalling problems were at the worst in the 70's. 318's used to have really bad stalling problem also during the 70's, again, caused by the Shi%^y carburetors and poor jetting.

I've always been told on those trucks not to overfill the gas, when the pump shuts off don't top them off or gas can fill the charcoal canister and cause the carbon to infiltrate the carb :?
