this weekend motor ran great all kinds of power and ect.. but later in the afternoon after a couple of beers started too take off all is fine and dandie till i noticed when i let off the gas pedal the motor would back fire through the exhuast... still ran great but is annoying as hell so now i need some pointers.. have new points in it, spark plugs,wires and coil ... timming should be at 30 dregs... i just checked it and readjust the points.. crarb is a progressive brand new... does carb need jetted??? or is the timming still altered a lil?? checked for vacuum leakes also nothing... dont see why it ran fine then started this b.s help or possily a valve issue

Could be your getting a little air in around the intake some where.after you get it running spray a little starting fluid in around the gaskets and boots and see if it speeds your motor up if so it's sucking a little air in and not sealing tight.this is just one thing it could be. Chad
