I have a 1987, 195-SunBird with a 4.3 OMC Cobra. I am trying to rebuild the carb. I found one the primary metering rods had been bent and restraighted (looks like a S). They are .045 and the main jet's are 71. I checked the straight one and found it to be .045/.026. but when I go on line to find some the .045 is a .045M making the lower end .036. Are these the oem needles for this marine carb? I can find info on older marine carbs but not this one. Secondary rods are DG. I'm worried if I buy what I have found I will need to change the main jets as well!!! Any one know were to get Delco Carburetor Model 4MV Quadrajet OMC Marine Data sheet for a 17085010 carb made in 1985?
