I must admit I haven't spent any time trying to learn how the IP works - I know it pumps fuel at high pressure to each cylinder in turn - and the timing is adjusted by rocking the IP toward or away from the engine. After rebuilding the engine I adjusted the IP because it was smoking excessively. It was a trial and error thing - Larry, . As to the timing of the pump, if you have compressed air at low pressure, the bubble method is really clean and dead on reliable. I think you are going to find that you are right on already, the way you describe your performance. I don't know why you are starting in 2nd gear but have to admit I have no experience with just a mechanical linkage (mine has a vacuum modulator too). Disconnect the long rod that goes to the transmission. Make sure the bushing in the lower connection is still there, an eighth of an inch play can throw this control off. Fix the bushing first. Drive the car like that. I would like to know if your trans responds to manually moving the shifter from 4 to 3 while coasting down from 50-60 MPH or so. Like if you wanted some engine braking while coasting down a hill. Then try shortening the short rod that pulls on the transmission rod bell crank until it does start in 1st gear. On mine, I have found that the throttle needs to pull this about 1/2 an inch BEFORE the engine speed changes. This lever is the ONLY way that the transmission knows to drop down to first during part throttle starts. Keep track of the initial measurement so you can get back to square one, even if it is wrong. Good luck, and let the list know if your first gear start returns. Jim Friesen Phoenix AZ 79 300SD, 261 K miles 98 ML 320, 138 K miles
