Removing all emissions stuff

Im about to remove everything under the hood of my 76 midget related to emissions control. This is a California car, so there is lots of it.. The PO removed the air pump but left the hoses dangling, and the air rail in place.

Does anyone have an opinion about which of these systems should be left in place, and if so, how they need to be modified to actually work.

I just put on a new header, so any system related to the old exhaust manifold is toast.

Any advice would be greatly appreciated.

none of it /ubbthreads/images/graemlins/smile.gif see my thread about removing the smog system and heater. I didn't leave any of it in place, engine runs great now.
 
Rob - I took everthing off and you are right the engine is purring....must be happier.... what did you do about the fuel tank vent pipe. So far I just left it where it was in the engine compartment.

Thanks

My 77 Midget sounds a lot like yours, Al. It had Kalifornia emissions, and it's P.O. had also done a "partial" removal job on the emissions junk. In addition to running better, it's nice to have a little more space under the hood.

Here's what I've been wondering... does the evap system really affect engine performance? It seems like the impact might be minimal, and it might be worth keeping this system hooked up to preserve some emissions control benefit. Instead of totally gutting my carbon canister, I've been thinking about rebuilding/replacing it and reconnecting the lines. Any thoughts?

I used it as the fuel return on the carb. I'll snap a pic tomorrow if you like.
 
Rob - thanks... I have a Weber DGAV carb on the car, so I may not have the same option.

When I get back home tonite I'll have a look.

Here's a thought, either plug the gas tank evaporation pipes in the engine compartment or go back to the tank and put a plug there. If you leave these open it is a direct opening for fumes from the tank and a little back fire in the carbs and the car and you become toast. What happpens is on a hot day or cold days it's less, the gas expands and the fumes come into the engine bay and the bonnet holds all in place. Not trying to be a smart a.., just want to see you around to enjoy your car. Wayne
