Leathermang,
I set the timing using the low pressure drip method and pumping the hand primer as it says in the manual like a mad-man. The timing was consistantly 22.4 each of the 5 times I checked it. The pump was at it's original factory setting indicated by what looked to be a chisel indent at the corner of the pump and the asing it sits in. I used this mark as a reference and nudged the pump over with the 4 other lines in place. I didn't neeed to use the special wrench as it says in the manual, I simply used a 13mm universal socket on an 18 inch 3/8 extension to get the one that looked initially impossible to get. That worked out pretty well.
I have a foreign repair shop in my town that has a bunch of scrapped Mercedes and I have gotten lots of parts from them including some injector lines that I cut down to make a drip tube that worked out well. I was even thinking of buying a bunch, cutting them down, and trying to sell them on EBay for 13.00 each, shipping included.
I now have an extra set of injectors that I bought from the same shop as well and I have them sitting in 100% biodiesel to see if that will clean them. If not, I will buy the gallon can with screen of carb cleaner as Larry Bible suggested and strip them down. I was considering getting the pressure tester for them, I saw it referenced here for 150. One of the members here was thinking about buying it to make some bucks, but I think he decided not to and I can't wait to mess with them. I wonder where I could get a set of shims for the injectors?
Take care,
Adam
