Well? I read your post and the replies.
I only decided to respond because I just took a phone call from one of my peers who is chasing a drivability issue on a classic car. Come to find out, after listening to his whole story and all the details about things he had done, he had overlooked one of the simplest items in the engine. Some commonly replaced parts that cost all of three dollars.
I hate to ask, but have you taken two, plain old aspirin to see if it helped?
My medical records say I was my own doctor too. But I really had to ask.
