Hello all hopefully somebody can help me.I have a 1986 chevy blazer it is backfiring through the exhaust.It happens while idleing and coasting nothing during acceleration.Little bit of history when I bought it I replaced the carburator as the original was in pretty bad shape I have replaced the exhaust fro the cat back 3" stainless new plugs new distributor checked timing set @ 4 btc has slight lack of power wondering if carb might need adjustment or what other things it could be. It sat all winter because I couldnt get it to run right.doesnt blow smoke except when you first start it.smells like it might be running rich. Last emision and inspection was ok emisions was within low ranges so I am a little frustrated and confused any help would be appreciated. Thanks in advance
