I measured the voltage when hot and it appears to be lean, .06 idling, .1 when revved with a .6 or so spike during acceleration. I still have the high altitude setup so if anything it should be running rich, which it isn't. how to fatten up a mid 80's mikuni, is there even and adjustment for the higher rpms? Re jetting right?

I remember when the float sank, boy did it run rich then, so I replaced it with a metal one and fairly sure that the level is still proper.

While I was at the boneyard I did pick up some of the little actuator diaphrams that attach in the carb. All the external vacuum controls are OK, but coould be connected wrong. I had a though time finding vacuum diagram for this engine. I went right to the dealer and couldn't get a conclusive diagram. I guess the best thing is to know how all the actuators and sensors all work together.

I just changed a vacuum hose around to lessen the draw on the advance and dumped a gallon of alcohol in. I'm getting ready to go get it hot and inspected. I'm still debating hooking the egr to a direct vacuum source to force it wide open all the time, at least for the test anyway. It works and actuates but may not open enough as I watch the diaphram move under different rpm ranges.

I had to check for values to make sure the O-sensor was ok and it appears to be.

Well wish me luck, I'll post the numbers when I get back. If it fails I get a free retest, so I may change the cam at that point, as I am suspect of the cam, I did't really like it when I built the engine, but it was the only one I had with clean bearing surfaces, and I figure it isn't to bad of a job to change later. Performance has always been sub par with this cam, but it is hard to argue with 19 mpg.
