Cant seem to get the timing adjusted right bought a new harmonic balancer replaced the carburetor every time I set the timing the carburetor starts back firing and the engine dies. Ive been having trouble finding some one who can fix it. Some one told me it may be the timing chain but Im stuck.

did u have that problem before you replaced hb and carb?
