Ser#H177B50961B
2L Mazda engine
LP low emission Aisan open loop system
Engine will not start unless assisted with a squirt of cleaner or partly cover the carb intake to richen the mixture. Recently replaced the LPG regulator, tune-up and cleaned the carb ( did not remove and dissemble).
Seems to be more predominate when cold. I'm not to familiar with this system but what controls cold start-ups, appears to be some kind of injector on the side of the carb (mixer).
Any help would be greatly appreciated
