Hello,

We have problem with engine starting and operation. It is difficult to start the engine and once it is started then we have following problems:
- unstable rpm of the engine
- backfire to intake manifold
- decreasd power.

Already done:
- air filter replaced
- spark plugs replaced
- LPG converter replaced

what special we have noticed is when it is difficult to start the engine if you detach balance line between LPG converter and mixer and blow air towards mixer through this pipe then engine starts without any problem. However, operation is stil bad.

Any ideas?
