Greetings Scions......... Does anybody else experience this "problem"? (I put that in quotes because I actually kind of like the effect I am about to describe). In my slightly tweaked Spitfire Mk I w/ 1147 motor, when I run it up fairly high on the tach (not to redline, just 3,500 or 4,000 or so), then lift off the throttle such as coasting to a stop light or behind heavy traffic (with the car still in gear mind you), I get a really nice terrific fat burbling sound with a couple of pretty good "pops" out the tailpipe (backfires). (Scares the hell out of little old ladies and dogs, and gets smiles from college coeds so I don't care to fix it frankly.) Question - what causes this? It sounds very much like some of the vintage race cars I have watched at various races, but I've never understood what causes it. I don't think it is a "true" backfire where the charge gets blown back out of the carburetor (or am I wrong on this point?). Does anyone else experience this? Thoughts please, Thanks. Ross D.
