What I have done: Replaced the Fuel Pump. Replaced the Fuel Filter. Swapped the Carburettor with another car of same make/model. Replaced the Resistor. Replaced the Dizzy Cap Replaced the Spark Plugs, and Leads including lead to coil. I am kinda out of ideas, the car is running better but still have this problem where it cuts out. Any ideas appreciated. Thanks in advance. Tom Greenleaf Ultimate Carjunky / Moderator May 3, 2008, 6:26 AM Post #2 of 3 (1425 views) Re: Stalling at Decelleration Sign In ? Open book of possibilities. Vacuum leaks anywhere at the age anything is possible - lines, connection, gaskets, diaphrams of all sorts. Also - any timing gears, chain or belt must be in spec, T brbettge User May 4, 2008, 10:16 AM Post #3 of 3 (1418 views) Re: Stalling at Decelleration Sign In i'll give this a shot. Is the car an automatic transmission? if so, there will be a dashpot on the carb. that allows the idle to come down smoothly. quick decels on these old toys would let them die if the dashpot was not working. dashpot is an enclosed vacuum diaphragm with a single hose port somewhere on it and an arm that attaches to the throttle shaft on the carb. there may be more than one. to check simply pull the hose off the dashpot; stick another longer piece on it and suck on the other end of the hose. if the arm moves then the dashpot is ok. another type will have no hose and will only have a pad contacting the throttle shaft on the carb. the pad should have resistance when pushed into the dashpot and return slowly to its rest position. Also on an auto trans car the idle should be set at 850-1000 RPM whereas a straight shift should be at 500RPM. The manual may say different but these are the best settings for the car. Does the car have AC? does it work and is it on when the car comes to an idle and dies? if so then there is also a vacuum control for this that keeps the idle high when the car returns to idle. The only other thing I know that will cause this is low fuel level in the carb bowl. you will find a small glass porthole on the bowl of the carb. the correct fuel level will be creating a "centerline" across the sightglass. if you can see no liquid thru the sightglass then the fuel level may well be too low. hope this helps, rick   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
