Sounds like a head gasket is giving up. Do a compression check, and research the parts you need to do a head rebuild.

Hardly anybody rebuilds carburetors any more. If you can even find a carburetor kit for the thing, there should be an instruction manual included in the rebuild set.

pull off ur egr an clean it or use a small bit of plate and exhaust paste and blank it it ill do her no harm but at least itll show if the valve is faulty r not

yes you should. use a small brush first and try to clean in behind the throttle plates inside as much as possible. then start the car, it may take a minute but it will start. then rev it up and spray some in the throttle. put a filter on it

White smoke during acceleration is usually the result of a "blown" head gasket. Antifreeze getting into the cylinder is the cause of the white smoke. Check the coolant level, if it's low you have the problem.

Engines backfire when timing has slipped. You might need a new timing belt. \

Timing belt goes from Crankshaft on bottom of engine to Camshaft on top of engine. Both have to be synchronized to the correct timing.

Check repair manual or internet for correct timing. You'll probably have to find top dead center on first piston.

this is caused by a blown cylinder head gasket.

Does not have adjustable valves . It has hydrolic valve lasher's . they are spring loaded ( i believe ) . I just replaced them in mine . valve giude seal's where worn out causing it to smoke realy bad ( looked like a mosqito truck ) and the valves where ticking , due to the hydrolic valve lash adjuster's being worn out . They are about $ 8 - 10 buck's each at advance .
