Auto-LPG Conversion Thread

[ghosthunter]

Is there a way to monitor the performance of carburator venturi kit if it is running on lean or rich mixture?

As i understand, one way is to physically check the spark plug of the engine.

Is there another way?

Well, there is the Oxygen sensor and meter retrofit. You can find these being sold on some online autoshops. $200+ prices though. If your car is alreadt equipped with an oxygen sensor, you can try looking for someone just selling the meter. I would advise you to get the self-heated oxygen sensor since still will give you a more stable reading. Single wire O2 sensors tend to jump around too much especially if the radiator fan blows air on it.

Or simply do the sniff test after you have warmed up your engine. If your engine is running correct, the exhaust should only smell lightly of LPG. If the scent is strong, you might need to clean the air filter or adjust the venturi system.
