Carburetor problems on A&M 40cc Engine
I have a 40cc A&M Engine on an Extra 300 airplane and it won’t start. I purchased a carburetor kit and installed it and I still was unable to start it, then I bought a new carburetor and It still won’t start. I also noticed a bubble in the fuel line. Could this be the problem and if so, how can I fix it?

Are you able to determine if the carb is pulling fuel from the tank ? If not ...
Common issues are:
Fuel tank internal plumbing problems .
Dry diaphrams in the carb .
Pulse hole blocked , failed gasket(s)or cracked carb insulator block.
Inspect all fuel lines and fuel tank internal lines . Be sure all connections correct and are tightly sealed .
Inspect the carb block and gaskets . Be sure the pulse passage is clear and all gaskets align with it .

Thank you for responding. when I installed the new carb, I also replaced the fuel lines too but I will check the tank and exchange it out. Also, what does it mean if there is an air bubble in the line, does this mean the tank isn't completely seal?
