You might check your carbs. They could be running rich. Mine were way to
rich. Because they were leaking air (need to be rebushed ) I had them set

Car would backfire and detonate when I would shut it down.
It was all fixed when I switch to Webbers
You can do a simple pressure check to rule out leaky valves.
