It would be interesting to find = out how Tracy found the problem and tracked it down and came up with a = simple fix. Oh yeah. The fix! Went down to Radio Shack, bought a 1000 = Ohm resister, 1/2 watt, installed it across the wires going to to the = CAS.

Tracy of course will be the last word on this. Thanks again = Tracy! That's why we call it Experimental! The engine sounds like a = car and not too loud. Also, B controller wouldn't run. Copyed A to B = and it started running too. 3 or 4 shots of primer at 35 degrees. No = cold start switch. Mixture at 2:00. No primer when warm. As I mentioned, It's running pretty well, but there is a mis, and it = seems to be at all RPMs. I had it before the latest fix too.

Any thoughts on = why I have this mis and what the solution might be? I assume that it is = an ignition problem rather than fuel, but my engine knowledge is pretty = basic. Also, I built my own intake manifold of 17.5 inches. Could this = be part of it, due to pressure waves, etc. One thing I haven't looked = at is switching the leading and trailing coils. I did it, to see if = it would still run on B controller, but not to see if the mis would = stop. I didn'nt notice it stopping if it did. Sure do like the heat = from the automobile heater core. I will be increasing the outlet = eyeball size. =20 Got rid of all my leaks. This is so nice! Running for a while at = 2600 rpm had 160 water and 165 oil @ 91 psi. I will be taking the fuel = system apart so I can drill and safety wire everything. Cool air ducted = to them. The Fuel pumps are very noisy and my ANR headsets don't cancel = that frequency out much. Are there quieter pumps out there? I will try = to sound deaden the back of the pump mount and the back of the fire = wall. Flo-scan fuel flow unit not working. EGTs not working. Love the = mixture moniter function.
