For a while now I thought I had bad gas. Or old spark plugs. Changed the plugs...no difference. Put in better gas, still issue but some better. Took the car over to,a friend who knows More than I do. He said take me for a ride. I did. Coughed, sputtered when other than just normal driving. He said I know the problem. Me surprised. Went back to,shop, raised the hood, he popped off the distributhr cap and said feel this..... bushings worn out giving some play to the shaft.
Ok, now looking for a distributor for the 440 with electronics not points. Seems to be hard to find unless you go for the red top dist. Not what I wanted to do. Still searching.
