Whew, THANKS BRENT! Should've posted sooner, but when we hung up, I was out the door, and your instructions were right on the money, plus, I did not have to bleed at the injectors. While I was waiting (not long, Brent) I did find this thread about this issue <A target="_blank" HREF=http://www.tractorbynet.com/cgi-bin/compact/showflat.pl?Cat=&Board=yanmar&Number=150182&page=5&view=collapsed&sb=5&o=0&fpart=>Click Here</A> to see it. The most pertinent (to me) of the thread was:

Mike,
The 186 is a cinch to bleed. When I was doing work on my fuel system I did it many times. Look for a combination 10mm hex head/phillips bolt. There should be two on the fuel filter assembly and one on the banjo fitting at the injector pump. Start with the one closest to the tank, crack it open until you get a steady stream of fuel with no bubbles. Then move to the next one nearer to the injection pump. After doing all three, it should start up. If it doesn't, you will have to loosen the high pressure lines at the injectors (just enough to let the fuel seep by at high pressure) one at a time and turn the engine over with the decomp lever pulled until you get fuel seepage. After everything is tightened back down it will start for sure. It's a messy process, but easy enough. I have done it in the dark before with a flashlight in one hand and a wrench in the other.
Best of luck, Jeff
Brent suggested I start with the one (mine only has one, at least hat I could see, and it worked) closest to the fuel tank (follow the line from the tank to the filter, then on to the "ball fitting", but sounds like the give away is the 10mm/phillips bleed screw if your setup is a little dfferent - take a wrench or socket, don't count on the phillips) then loosen until bubbles quit. in my case there were about 3 sets of clear, then bubbles again - better to spill a little more diesel (you will) than stay frustrated. That's all I needed to do, fired right up, no hiccups. But, if that fails, move on to the injectors, loosen the injector(create a leak) and wait until bubbles stop, then move to the next. Move from the tank forward (from above). He also said that it might be helpful to have someone there to crank the engine to create pressure to force out the bubbles, again I did not need to.
Brent (and others) Thanks for making what could have been a super frustrating event into a nothing event. I almost wish you hadn't helped - with the tractor outside, SURELY it would have rained!
