I figgured that to be the case. I am going on the assumption( I know
don't assume anything) that by just swapping in the MC FD onto
the UR-Q airbox contraption, the fuel metered using larger slits in
the FD, would give the correct amount for fuel for the MC engine.
I know I will have to tweek the CO adjustment and play with the idle
speed, but I should be in the ball park. I can hardly wait to play
with the sunpro.

At lunch today, I stopped by a shop with its own private boneyard and
checked out the air cone on a twisted 87 5kT. Transfered the dimensions
onto a cash register receipt for comparison with the UR-Q funnel and
will report back.

And PDQSHIP, thanks for all the part numbers. I didn't know that
the injectors used on the 83 ur-qs were different from the 84-85 ur-qs.
This brings us to the question of whats the part #s for the mursaidis
 upgrade squirters?
