OK I know this is probably fuel related but here goes and I did search for this. I have been OCONUS for about 3 months (none use of any vehicles). Started the 89 IDI really no issue starting (2 GP cycles) but it had a "clatter", I bipped the throttle it settled down and chugged contentedly at initial higher idle to idle down (op temp), It has done this off n on since i have owned it more off then on and especially if your trying to demonstrate to some one the noise. Since driving the past few days it seems to be more consistent, usually at start, or coming off throttle downshifting for a light. Bipp the throttle and it goes away. Normal Acceleration no issues she pulls pretty good for an IDI, It has about 400 miles on an oil and fuel filter change. Runs and idles good except on the occasional "clatter" episode (69K miles) on original motor. Fuel filter/pump are stock, no leaks (im pretty sure its not air cuz she fires right up) am I correct in thinking the only fuel pump is the one mounted forward on engine? no pumps in fuel tanks?
