Ok this isn't anything I saw in the tm today. What is the best way to bleed and prime it??
My guess is that you have air in the high pressure injection line because it was not fully primed after the filter change and cranking it got air in the injector line. With air in the line it will balck or blue smoke as the delivery is very retarded due to air.
To Thouroughly bleed: (This is procedure works for a completely dry system)
Make sure there is enough fuel in the tank so that the Fuel control solenoid retracts at the pump lever when the switch is turned on.
Open the bleed thumb screw on top of the filter housing. When you move the prime lever feel that it makes some resistance before the end of the stroke. The transfer pump is cam driven and if the engine cam is pointing up the stroke of the primer lever will be little to none. Jog the engine a few times with the starter trying the primer lever until you feel a pretty solid stroke on the lever. This will allow maximum fuel per priming stroke which is what you want.
Now prime it until fuel comes out of the bleed screw. I have done this a bunch of times on many many different units and I used to say 100 to 200 strokes and it will fill the filter and push fuel out the bleed screw hole. Well I just did a 701A last week and I swear it took 400 strokes! When fuel comes out the screw hole, and it eventually will, then close the bleed screw and prime it some more with the fuel tank fill cap off. Listen carefully and you will hear fuel droping into the tank from the prime system.
Now you have solid fuel and no air at the injection pump and solid fuel back to the tank. Next loosten the injector line at the injector turn the switch to start and crank it until you get at least 10 strokes where there is good squirting of fuel coming out. Make sure the fuel solenoid has retracted at the injector pump so the pump is set to max fuel when it is being cranked.
Tighten the injector nut and it should fire off pretty quickly with normal start procedure!
P.S. I have found it necessary to prime the 016B if they sit a few weeks to a month. They seem to loose their prime moe so than other engines.
