M.P.G. poor

[jpliddy]

hi all
following on from my diesel leak .which garage fixed but left me with poor M.P.G.
well today i adjusted the smoke /fuel screw 1/8 of a turn and had a friend follow me on open road he could not see any real smoke when i floored the accelerator
only a slight puff once .so do i just the screw another 1/8 turn and see what that does . power was there better i think he said power was good as he was impressed with acceleration . i won't be able to tell for a while of driving if M.P.G.improves . as you said with this its a little bit at a time till i find the right balance .
when i loosed lock nut a little the slotted screw will turn clockwise even with the crimeped sleeve on the threaded screw !
any comments most welcome .
regards jim
