Tracy,

That is EXACTLY what is was. The = contrast=20 control knob had not been hooked up yet as it got late much faster than = I wanted=20 it to. So, I went out there after work today and installed the = knob,=20 twisted it and up came little numbers. I can't tell ya how = beautiful it=20 was.

The manual speaks of a LCD backlight = dimmer=20 switch , but I don't have it. It is just a common switch or = is=20 something special? If special, I will want to get one from ya when = you=20 return from you trip. If not, can you tell me what to look for = locally=20 please.

Now to start trying to figure stuff = out...what is=20 working and what is not quite working. The engine seems to start = easy one=20 time and then not the next (maybe flodding?). Also, when it is = running,=20 the rpm seems to be jumping all over the place. Mostly in the 3000 = rpm=20 range...at least that is what I am shooting for, for now, but it will = jump up to=20 6000, then 8000 back to the 3000 range in a very inconsistant = manner. When=20 I add throttle it goes up, but still seems eratic. I am = getting=20 ready to read the manuals again now that the pieces are starting to fit = together=20 and see if the mist will clear a bit.

Man, without anything but a straight = pipe (actually=20 a turbo exhaust w/ waistgate opening and the tubo mount flange blocked = off with=20 a metal plate) this engine is LOUD. It does make is sound very, = very=20 powerful though <g>.

Again, thanks Tracy and all the rest of = y'all. Your continued input is very reassuring.

All the best,

Chris

Chris,

My guess is that if you do have power, the EM2 either has the = contrast=20 control turned up too high or is mis-wired. First twist = the=20 contrast control to both ends of travel and watch the display. = If still=20 no joy, check wiring. You do have the contrast control = installed,=20 right? Only the LCD version uses this control and yours is = an=20 LCD. Normally the contrast control will be turned fully CCW = unless the=20 temperature is really hot or really cold.

PS: Don't be bashful about using the mixture control on the = EC2. Turning it is the fastest way to get an education on how = the engine=20 reacts to mixture changes. Every pilot NEEDS this education on = an=20 experimental engine. If it runs better after you turn the pumps = off,=20 it's telling you what you thought : (TOO RICH).
