I ordered a new carb and new petcock cause when
I sucked on the vacuum line of the old petcock I
Was getting fuel through the vacuum line, just
Installed everything and still won’t fire what am I doing wrong?
I have the fuel line going from the petcock to the
Carb and the vacuum line going to the intake fuel lines aren’t clogged
Even tried spraying starting fluid into where the air filter goes and got nothing
Also checked for spark again and I have spark, I don’t know what to do
