Answer
Hello Mizan,

Sounds like fuel starvation. Check fuel cock and filter for free flow.

Then try, with the fuel reservoir uncovered, so to be sure that it breathes freely.
It is very common, that the breathing hole on the filler cap is clogged and the fuel flows
too slowly to catch up with the engine demands.

Try this and get back to me with results.

Best Regards,
Lazaros.
