Thank you everyone for so much help and support. I did put the engine on the test bench after cleaning all the needles and passages.
The result was the same . So now i have ordered the spare parts. I also have another 50 cc from Da i am facing similiar problems. So i will have to wait till i change the pump.


Thank you everyone for the valuable suggestions and help.I will get back in 15 days time once the spare parts arrive(customs).
I really appreciate the help without which i could not have understood this problem.

Merry christmas and a happy new year in advance.

Regards,
Varun
