well, even "cheap" open loop venturi mixer LPG kits can be problem free. Take my car as an example. Generally reliable & efficient as long as you maintain the air filter well cleaned.

One major advantage of "cheap" venturi-mixer systems is the owner/driver can make adjustments to the system right on the spot (if you know what you are doing). Of course, just be careful because it's easier to screw up your LPG settings than getting it running correctly.
