Like the title says. The truck will not start, it cranks fine but while cranking sometimes it will spray gas out the top of the carburetor or backfire through the exhaust. Could the timing be the issue? I got it to top dead center, I didn’t set it 12 btdc. Could this be part of the issue? Possible sticking valve? Thank you for anyhelp provided.
