Somebody’s jalopy can’t start. Its a 1.6ltr engine with a carburetor. Spark-check, fuel flow-check, the problem is that its not sucking air by the carburetor.
Thought it is flooded but when u cover the carb it’s pushing air out instead of sucking it.
Loosing compression, check for leaking gaskets.
Ukiangalia the carburetor how is the floater mechanism behaving,
I know how to tinker a carb but I lack the words to helep you.

you got a major valve or timing issue. the wrong valve is open when the piston goes up or the valve is open at the wrong time if its a two valve per cylinder.
