Timing Advance Processor for Carburetor Engine

[qtzaman]

I have coverted my Mitsubishi Lancer 99 Model (1.3 Ltre, 4G13 Engine, 12 Valve, Carburetor Type, 5 speed Manual Transmission) into CNG. Now, i am not getting my expected performance. The engine speed is quite high in stationary position. I have used lo.gas (Italy) CNG conversion kit and Inflex (Argentina) cylinder.

Please advice, do I need to use a Timing Advance Processor?

Hello!
CARB car won't need TAP(Timing Advance Processor)........
the timing can be advanced through Distributor mechanically bu adjusting it......
as u said engine RPM's are quiet high on IDLE...so there a adjustment screw near Throttle from which u can adjust idle RPMs of engine........!
in what sense ur not getting the performance...?
Thanxxx

well you can live without a timing processor in carby cars, but then your car will knock on petrol caz you cant get the best of both worlds...
advancer can be and is being installed in carb cars, all ff cng lineup from suzuki have them....
