Choke is stuck in 86 olds cutlass supreme chugs and doesnt go

The catalytic converter is in the exhaust pipe and is the smaller of the two. One is the muffler and it is usually in the rear of the car and the catalytic converter is just behind the o2 sensor in the same tailpipe. Close to the exhaust manifold.

Not really.
You have to cut the old muffler off and reconnect the new one, either by pipe connectors or by welding it.

Have you rebuilt the carb or checked to see if the choke was stuck or working? Those would be good starting points.

mines is a v8..so its a 5.0 liter 307..u can tell on ur vin number tho..it should have an h or y check ur manuel for the complete list...

mcdevito75 here, I don:"t think there is a fan belt changeing diagram for your 86" you can order the new belts and mark them Water pump, alternator, power steering. as you order them. The power steering pump is the most difficult to loosen and tighten, you"ll also need a crowbar to hold the various units tight after you install the new belts as the belts can"t be too lose nor too tight. Best bet let your local shop change the belts they last a good while and you have the piece of mind all is adjusted correct.

better off with a electric choke, and make sure the vacuum choke pulloff is working ,

make sure it's tight!

fit a new tank or get some glue called "tank weld" its like a putty and will stop the leak dead in its tracks im gessing its rusted through?

This car uses r12 freon that is the old stuff but you can have your system converted over to the 134a.

Well, you are either not getting enough gas or air. First try taking off your air cleaner and then try to start your car. If that works than just buy a new air filter. If not, try repulsing your fuel filter. Should be under the car between the gas tank and engine. It is a cheap part but serves its purpose. Also you should replace your spark plugs and wires just for regular maintenance. If that doesnt work it could be either the fuel pump or carb. if you don't know that much about those, don't try to monkey around with it. Have a friend or a shop do it. But,,,, before you pay out your *** for unnecessary shop work check out prices for a new carb or fuel pump.

Your problem is could be one or more of those things. And for the very worst scenerio, could be a blown head gasket. Check out the easy stuff first and work your way to the others
