MG MGA - Won't Idle Down
|Car has been running great but recently I have noticed that while driving, if I let off the gas, the engine speed does not idle down quickly, there is almost no engine braking. If I depress the clutch, the speed will go down rapidly, but not while engaged.|
I checked the pistons and they drop and clunk like they should. Any ideas?
|Maybe the return springs on the ends of your carbs. throttle shafts are faulty, broken or just too weak. I had a similar problem but with my mixture control not returning and replaced the jet lever return springs. The new ones were three times stronger than the old! I suppose they weaken over the years.|
Or perhaps the inside throttle cable is frayed. You could try disconnecting the cable at the carbs. and feeling how free it is from the pedal end.................Mike
|I had this problem when I had a bad gasket that was letting in too much air. I took everything off but the manifold and replaced all the gaskets from the manifold out and then the car would idle down.|
|Have you checked the engine compression since this problem started?|
|Lots of good ideas. I just insulated the cockpit so I need to make sure the throttle pedal assembly is not binding anywhere, check the springs and then look at gaskets. Oh, and check compression.|
