I have a 33cc 2 stroke chainsaw engine the carb on it has 2 lines one is smooth the other has barbs. My question is which is air intake and which is the gas. I would think the barbed connection would be for the fuel. Thanks for your help.

Hi tinker
There is no air intake line
They are both for fuel and you have 2 lines going into your gas tank
The way those Walbro diaphram carbs work is that one line is for
fuel coming into the carb and the other is to return excess
fuel to the tank
as there is no float bowl to store fuel on the carb
