What is important is to find a compatible carb for the specific engine you have. In my case, it's a 188F 13HP petrol engine. It's a Chinese clone of the Honda GX390 so parts are interchangeable. This engine is commonly fitted on many 5-7kW generators.

Wala na yung listing nung pinagkunan ko. Here's a close match: https://shopee.ph/LPG-NG-Carburetor-...b-7c747d2ee7d9

The regulator I used is this Tokina snap-on type for Gasul tanks. https://shopee.ph/%E2%9D%A7%E2%98%8B...8-81d9eb77e269

DO NOT buy regulators that has a safety "anti-explode" feature. You'll be subjecting yourself to a world of frustration if you do. Ask me why I know that. ;)

Swapping out the carb is very easy. Disassemble the air filter box down to the carb nuts. Remove the fuel hose from the inlet on the carb (make sure that the petcock is off) and slide out the carb. As you pull out the carb, take care not to damage the gaskets and speed governor linkages. Unhook the latter and set it aside.

Installing the new carb is just the reverse. The rest is pretty much self-explanatory. ​


Starting on petrol:
1. Turn on the petcock and wait 5 seconds
2. Turn on the choke
3. Start the engine
4. Once the engine is running, turn off the choke
5. To shutdown the engine, turn off the petcock and let the engine starve itself of fuel. This make sure that little to no gas remains in the fuel bowl

Starting on LPG:
1. Turn off the petcock
2. Drain the gasoline from the fuel bowl (skip if you did step 5 above)
3. Make sure that the orange knob is set to LPG/propane
4. Turn on the LPG supply at the tank side
5. Turn off the choke (LPG doesn't need choke to start)
6. Press the purge button on the on-demand regulator for 2-3 seconds (that cylindrical thing under the new carb).
7. Start the engine
8. To shutdown the engine, turn off the LPG supply at the tank

If the engine is running rough:
1. When on gasoline: Make sure that the choke is off and that the governor linkages were installed correctly
2. When running on LPG: Adjust the LPG fuel mixture by slowly turning the screw inside the orange knob left or right, whichever makes the engine run smooth. Also check the governor linkages.

Dami videos on Youtube. Here's a start
Ano yun sinasabi mo meron ka na trim? Ilan hours yun isang LPG tank na pagbahay?
