Hi Gary. Thanks for the reply. Yes, it's not drilled and with secondary metering plate. But my doubts are:
- Fuel getting old if it's in there for month (OK not really a problem).
- If the fuel found a way to that chamber maybe it will find a way to a idle port, and some unwanted gas going out.
I checked carb body, that steel plate & metering plate, not one is warped. All gaskets are in good condition. No clue where it's going through. Denis
