It's not that there isn't enough vacuum. The restriction caused by the AFM causes the engine to suck too much LPG out of the mixer, so it runs very rich. I proved this with the Lambda sensor + readout that I have in my van.

remember it's only a bodge if it DOSN'T worK
It's not straightforward in the least.
Getting the mixture right is just as important as setting up the right timing and the extra advance to compensate for the slow flame front of LPG.
The power screw can be turned down but you start to get into all the probs of having to reduce the output screw on the vapouriser as well.
Turning down the Vaps output and balancing with the power screw in the vapour feed pipe should help.

Hi DD , i have one of these
http://cgi.ebay.ph/Autogas-Lpg-Lambda-C ... dZViewItem
not bad , i have left the unit with the flashing lights on attached to the unit and fitted to the dash ...
red light =too rich
green light =too lean
i have put it back like the picture for the minute ...ie:
airfliter -- mixer -- AFM -- backfire -- plenum .... etc
and it runs fine ..
