Tracy,
             You were right about the slide throttle, was ready for the test 
flight and my mate pushed himself into the back seat trying to open the 
throttle. I had done all the mapping with the screw vernier, never trying to 
push it open.  He called my parentage into account and left me to "fix it" 
With the engine stopped it worked beautifully, start the motor and it locked 
solid.  So it is now to be replaced with twin butterflies as you suggested.
    A few further  questions,
1.  The AL channel does not seem to exist.  Have tried many times to find 
the course of the alarm light going off, and nothing whatever!
2. The EMC still tells me NOP occasionally for no apparent reason???
3.  To set the fuel flow from gals to litres  3.78 times, it would appear 
from your book that I should start in parameter 2 (course fuel flow) rather 
than par. 0 as suggested. (fine fuel adjust) ??
4. to set the fuel quantity according to your instructions is impossible. 
Hold 1 - press 3, so far so good. Then it says to press  3 (Abort) which it 
does.  I find I have to press 4 (ack) first and then it all comes good.  Is 
this the correct way??
   Neil.

I use 1/8" ID silicone tubing for MAP lines.  Truly high temp capable.
