I took some picture of the engine on how it is connected right now. It will start but sounds horrible. I know that the hose connected from the canister to the carburator are correct. I am not sure what the egr/purge tcc tvs is. Is the one that comes staight out from the top of engine next to the thermostas housing. If so I am not sure how they are connected. I was unable to locate a delay valve, decel valve, efe, distributor delay valve, or efe/distr tvs. Don't know what those look like.
