hyundai excel 1993 running rich
 

I've just put a recon motor in my hyundai excel 1993.
It is a dual fuel and runs ok on lpg but on petrol runs very rich.

If when accelerating I just back of throttle it will run clean but the
slightest increase in throttle causes lots of black smoke.

A local auto repairer is looking at it.

We have swapped oxygen sensor, throttle position, MAP sensor, checked temp
sensor and still no go.

Error code showed oxygen sensor error but suspect this was because it was
running so rich.

Could only check output fuel pressure from fule return but seemed ok.

Any ideas for further check

Regards

Being overwhelmed by the response I did more swapping.

plugged in another injector rail and injectors and away she went.
