I have a 1963 Ford F100 with a 292 in it.  My family is the original owner of the truck and everything on it is stock.  When I drive the truck it always smells like gas.  I can't even park it in the garage because the odor is so strong.  The truck runs okay as far as I can tell.  I don't know that much about engines but I am mechanically inclined and can follow directions. 
I adjusted the valve lash but there is still a loud ticking noise from the number 1 and number 2 cylinders. 
I am not really sure where to begin but I thought it could be an issue with the timing. 
I have tried to find a video on how to adjust the timing but I haven't found anything with enough detail.  
Can anyone tell me how to adjust the timing or point me to a good resource.
Any help is greatly appreciated!
