40 hours since factory. Dumped on my lap. The engine was never set up properly at installation (done elsewhere). Don't you hate trying to correct someone's laziness/incompetence/insert your own reason.
Now have the unmetered fuel flow right at top and bottom. MAP's now match throughout the range. Now have 25 RPM rise on ICO. All seems good.
Problem remaining....
Cannot get the indicated fuel flow up at the bottom end of the range. Doesn't even reach the green arc until around 1500 RPM. Everything matching nicely between the engines once RPM's at or above 1900. Nothing in 97-3C seems to help cure this problem.
I am probably missing something blindly obvious, and will take any constructive critisism/pisstaking on the way to remedying the fault.
Over to you all and thanks in advance.

One thing though
,I got a TSIO 520WB new from the factory and that came with short reach plugs instead of the correct long reach items, had all sorts of probs with that, when the second was fitted by another company I heard they to were having issues in flight as it was misfiring to death, they had tried everything under the sun, I contacted them told them to check the plugs and guess what............ yup same thing even after we had informed the factory twice.
